Considering the cost of time driver and passenger car in the technical and economic assessment

Bogachenko V.M., Goncharenko M.V.

The paper considers an approach to determine the estimated value of hours of time road users, based on the use of fuel consumption, depending on the speed of vehicles.

Today highways are built or reconstructed only for public funds. Since funding of the field is limited it is necessary to legible define the areas of roads which need the reconstruction.

The numerical value of the value of time used in the technical and economic assessment of the project making new construction and reconstruction of highways.

It is proposed to consider the approach to the valuation of time for drivers and passengers, which is based on the dependence of fuel for cars.

Despite the fact that the roads today there speed limit of 90 km / h, drivers exceed this value (to the extent permitted), indicating that travel time savings of the road for drivers of identical additional fuel costs. Therefore, we consider acceptable as the estimated value weighted average cost of adoption, which will depend on the distribution of vehicle speed traffic flow.

The estimated value of this approach for time road users is a variable that depends on the difference in vehicle speed and the largest permissible speed. For the correctness of this approach is recommended to apply the weighted average cost of time to be determined based on the distribution of vehicle speed traffic flow.

Different type pendulum type dynamic vibration absorbers application

Vikovych I.A., Diveyev B.M., Martyn V.Y.

The paper deals with the methods of calculation and optimization of pendulum type dynamic vibration absorbers for elongated elements vibration decreasing. The discrete-continue models of elongated overall elements based on Timoshenko beam theory with the attached discrete elements are offered. The algorithms for vibration decreasing of elongated machine elements are received.

Noise and vibration are of concern with many mechanical systems including industrial machines, home appliances, transportation vehicles, and building structures. Many such structures are comprised of beam like elements. The vibration of beam systems can be reduced by the use of passive damping, once the system parameters have been identified.

Dynamic vibration absorber is found to be an efficient, reliable and low-cost suppression device for vibrations caused by harmonic or narrow-band excitations. In the classical theory of dynamic vibration absorber, the primary structure is modeled as a spring-mass system; however, other models also have high interesting research and engineering application. In particular, the pendulum type system occurring as a model of a solid body with a fixed fulcrum point can play an important role in many fields such as machinery, transportation and civil engineering. The effect of a dynamic vibration absorber on a pendulum structure with the impact masses can be very different from that on a spring-mass system.

The main aim of this paper is different type dynamic vibration absorbers investigation and optimization. As the model of many actual systems in the literature, Timoshenko beams with various supporting conditions and dynamic vibration absorbers of various type are used. Methods of decomposition and numerical synthesis are considered on the basis of the adaptive schemes. Design of elongated elements of machines and buildings in view of their interaction with system of dynamic vibration absorbers is under discussion. A technique is developed to give the optimal dynamic vibration absorbers for the elimination of excessive vibration in harmonic and impact forced Timoshenko beams system.

Gordienko V.P., Mustyatsa O.N., Kovalyeva G.N.

Comparative research of structure on the different levels of its organization and complex of physical-mechanical properties of linear polyethylene (the LP) under the influence of dispersible and nano-sized titanium dioxide, and also ultraviolet radiation, on the obtained composition materials has been conducted in this paper.

Linear polyethylene (the LP) with medium viscous molecular mass 9,5×104 and with degree of crystallinity of 54% has been the object of this research. TiO2 of rutile form (R-1) with particles of not less than 1 micron and general surface of 3-7 m2/g has been applied as dispersible admixture. Synthesized TiO2 with general surface of 77 m2/g and particles size of 30-50 nm has been used as nano-sized admixture. The admixtures in the LP has been brought in an amount of 0,1-3,0 vol.%.

Tapes with the thickness of 50 5 mkm and pills with the thickness of 3 0,1 mm and 10 mm in diameter have been made from these compositions using the method of hot pressing during 20 minutes with pressure of 35 MPa and at temperature of 443 K. The polymer which didnt contain admixtures has been processed by the same way. The samples have been influenced by the unfiltered radiation of mercury-quartz lamp of DRT-1000 in the atmosphere of air during 20-120 hours at temperature of 298 5 K with periodic turning.

Infrared spectroscopic study has been conducted on the spectrophotometer Specord M-80 with the use of differential method of infrared spectrums recording.

Determination of content of gel fractions (stitched molecules) and amount of graft-polymer on the particles of admixtures have been carried out by the way of extraction of the unbound molecules of the LP and free parts of titanium dioxide by boiling toluene till the permanent mass of remain.

Radiographic examination of crystal structure of the LPs samples (degree of crystallinity and height of fold of crystallites) has been made on diffractometer DRON-3. The average sizes of spherulites have been determined by optical-microscopic method on thin films with the help of polarization microscope of MIN-8.

Processes of melting and crystallization of output LP and the LP, that contained the admixtures of titanium before and after ultraviolet radiation, have been studied by the method of differentiated thermal analysis by derivatograph Q-1500 D. The accuracy of determination of temperatures of melting and crystallization of the LP was 1 K.

Destructive tension during stretching (σ) and relative lengthening at a break (ε) have been determined as physical-mechanical properties of compositions of the LP, speed of stretching of the samples was 6,6 × 10-4m/s.

Hardness of the samples of the LP has been measured by the method of Brinell. Because of limitation of influence of ultraviolet radiation on the layer of polymer ~100 mkm, the values of microhardness of surface of the samples of the LP have been determined by the device of PMT-3. Values of seven parallel samples have been used for calculation of physical-mechanical characteristics of compositions of the LP.

The fundamental basis of open intelligent information systems

Danchuk V.D., Lemeshko Y.S., Lemeshko T.A.

The paper proposes the fundamental basis of open intelligent information systems (IS) based on synergistic principles.

Purpose to present fundamental basis of open intelligent synergistic information systems.

Research methods methods of system theory; the theory of analysis, simulation and optimization of management processes.

Most existing intelligent IS offers adaptive technology to adapt management processes to the needs of the user in accordance with parameters of his profile. However, usually they do not take into account changing demands of the environment. In this way, significant results were achieved in the field of a synergetic approach that examines the general patterns of cooperative effects accompanied by the formation of new spatial, time and functional structures due to non-specific external effects of self-organization. The authors proposed a new structural model of open information intelligent IS based on synergistic principles.

As part of the open intelligent IS methodology it is determined that the dominant role in the development process has moved from the negative feedback mechanism to the positive feedback mechanism (positive feedback between the order and control parameters), the effects of self-organization.

The proposed approach can solve the organizing and intellectual tasks to manage processes for large amounts of unstructured or semi-structured information coming from outside the system.

Forecast assumptions about the object of study the search for new effective approach to apply in the field of open intelligent information systems.

Object of study CdSe plate crystals.

Purpose of the study to determine the effect of the dye laser radiation intensity on form the CdSe edge of the fundamental absorption band.

The method of the study - an analysis of the nonlinear transmission plate single crystals of cadmium selenide.

In the linear optic transmission medium is independent of the light intensity. It was established that this state of CdSe kept up to intensity £1000 W/cm2. With further increase pump intensity there is a nonlinear increasing transmission with further access to the area where the transmission does not depend on light intensity (state of absorption saturation). Using the known value of the sample thickness and values of transmittance at low and high levels intensity, we is found absorption coefficient for different wavelengths of pump. These data allow us to determine the CdSe shape of the absorption edge in the region linear optics and in saturation state.

It is found that in Urbach spectrum region change absorption occur due to filling by carriers potential pattern, which is created point defects, but not potential pattern created by thermal vibrations of the lattice atoms. In the region of interband transitions change absorption occur due to filling by the bottom of the conduction band.

Results articles provide new knowledge about the influence of laser radiation on the properties of semiconductors and can be used in predicting the characteristics of optical switches and optical transparencies.

Forecast assumptions about the object of study the search for optimal performance optical switches.

The article is dedicated to study of the issue of extending of pavement season applying warm asphalt mixtures based on solid hydrocarbons that provide adequate compacting at low temperatures and reduce damage of the structure due to the lower cooling rate.

Object of the study asphalt layers of warm asphalt mixtures produced using solid hydrocarbons.

Purpose of the study researching of the possibility of using warm asphalt mixtures produced using solid hydrocarbons to extend the paving season.

Research methods analytical and experimental.

The results of theoretical and experimental studies of spectral phase transition temperature and the kind of n- paraffins binder shows that with this transition there is a sharp change in the nature of the molecules in the crystal grid. Molecules due to thermal excitation are carried out vibration and rotational motion. This leads to changes in structural and mechanical properties of hydrocarbon components of bitumen in particular, abrupt, several orders of magnitude, reducing their viscosity, even at temperatures below the melting point. Introduction hydrocarbon plasticizers (Rediset WMX and Sasobit) in bitumen, due to the formation of certain chemical bonds leads to an increase in the temperature range of existence of the orientation phase, and thus increase in the temperature range of plasticity and deformability of bitumen. Therefore, we can assume that one of the factors that determine the appropriate rheological properties of bitumen is the existence of a certain range of temperatures rotational phase of hydrocarbon components.

Physico-chemical affect of sodium sulfide on conductivity nature of molten multifunctional conductors

Mustyatsa O.N., Lisin V.I., Kovalenko I.V.

The review of experimental investigations for the chalcogenide melts with mixed ion-electron electroconductivity showed the Sodium Sulfide as perspective heteropolar additive.

The value of electroconductivity for the melts of antimony, iron, nickel, silver, thallium, lead and tin sulfides at Na2S adding becomes essentially lower and the character of electroconductivity temperature dependence is changing. The values of electroconductivity and type of it isotherms are the evidence of decreasing of electron deposit in electroconductivity: at ionic additive content increasing all isotherms become linear, what is typical for the conductors with primary ionic conductance.

The essential electrode polarization takes place in all melts with primary ionic deposit what testify to electrochemical efficiency of such systems. However, voltohm curves have the regions of sufficient residue currents, what can be explained by the presence of some electron conductance in melts. The preservation of residue electron conductance is connected with the character of chemical bond metal sulfur.

The essence of heteropolar additive affect on the nature of molten multifunctional conductors conductivity can be explained by the transformation of chemical bond nature in melts and by changing of mechanism of electron transfer from zone to jumping.

Electrochemical investigations and electrolysis for the systems of molten multifunctional conductors Na2S allow to determine, that the metal current exit from the melts is increasing, such as for systems: Sb2S3 Na2S (Sb current exit 63,5%), FeS Na2S (Fe 29%), Ag2S Na2S (Ag 56%). The practical recommendations for electrolysis were formulated for systems: Tl2S Na2S, PbS Na2S and SnS Na2S.

The research of possibility of utilization of electrolytic processing of fusions of dump industrial antimonial mattes on metal antimony

Mustyatsa O.N., Yankovich V.

One of the most important actual problems of metallurgical branch is the one of processing of dump mattes that represent alloys of sulfides of different metals. They tend to accumulate and gradually make the whole ranges of ecologically dangerous substances.

The conductivity of fusion of dump industrial matte of iron, antimony and sodium of Kadamdzhaysky mill has been investigated for the purpose of utilization. The course and quantity of conductivity of matte are typical for multifunctional conductors with dominant semiconductor mechanism of conductivity. It has been shown that introduction of a heteropolar additive (Na2S) in fusion of matte is accompanied by suppression of not ionic component, and then conductivity falls up to the quantities of ionic fusions. It has been established that the minimum of conductivity in system of matte Na2S is observed for the structure containing the 60% pier Na2S in relation to FeS.

Volt-ampere characteristics for the structures of system supporting 60% and the 70% pier Na2S have been investigated. Polarizing curves have accurate breaks, and that can be connected with electrochemical decomposition of Sb2S3, FeS and Na2S.

A large number of experiments on electrolysis of fusions of system of matte Na2S have been carried out. Sulfur release was observed during those tests.

Still it is impossible to draw an unambiguous conclusion on expediency of application of electrolysis for processing of dump industrial mattes on metal from the conducted research. It is necessary to proof this technology economically.

The need to clarify the calculated characteristics of soil in justification of project decisions in the reconstruction and overhaul of the roads

Shulyak I.S.

This paper discusses the need for clarification of the design characteristics of soils in justifying design decisions on reconstruction and capital repairs ofthe roads.

Object of the study road construction.

Purpose of the study comparison of the calculated and actual soil characteristics on specific areas of roads.

Method of the study methods of the theory of elasticity, finite element method (FEM), field trials.

One of the significant factors that lead to the destruction of road construction is mis-accounting of the actual state of soil subgrade in the design of pavement.

Using tabulated values ​​of the design characteristics of soils given in national regulations, leads to the fact that design decisions on reconstruction and capital repairs of highways often not well-founded.

To establish the degree of discrepancy between estimated and actual characteristics of the soil in specific areas of roads at different times were measured actual deflections surface coatings in the billing period. In the vicinity of the measurement points were selected cores, which were determined by the thickness of the structural layers of pavements on the selected sites.

For the calculated values ​​of the elastic deflections of pavement structures were brought to the two-layer system. The maximum elastic deflection surface of the two-layer system obtained from the calculated load is determined by the formula Barbera.

In addition, the calculated values ​​of the elastic deflections are determined using the finite element method using the software complex SCAD with the same initial data.

The results of the comparison of the calculated and actual deflections surface coatings have shown that in most cases the actual values ​​measured deflections surface coating on the test plots far exceed deflections calculated using the following in VBN V.2.3-218-186-2004 table data on the deformation characteristics of soils and pavement materials.

Detailed field testing of soil need to be performed to take a more informed design decisions in the reconstruction and capital repairs of the roads.

Routing of international road transportation of dangerous goods

Shurupov V.O.

In this article an approach to the problem of dangerous goods road transportation network synthesis is proposed, the results of routing methods analysis are given, and the values of characteristics and parameters of dangerous goods transportation process are defined.

Object of the study dangerous goods transportation process.

Purpose of the study to define a procedure of road network routing for dangerous goods transportation, to justify the routing methods, and to define the parameters of international road transportations of dangerous goods.

Methods of the study system analysis of road network synthesis methods and transportation routing and statistics analysis of transportation process.

The dangerous goods road transportation network of Ukraine is formed without a sufficient substantiation, it has no identification signs, it is not provided with appropriate infrastructure. Therefore, the problem of the appropriate network synthesis that accounts for the limits of road vehicles traffic and the value of investments in infrastructure development requires a solution. In order to solve the problem, the procedure of directed option examination for a complex criterion of maximization of the difference between the value of possible effects and the costs those are required for the development of road infrastructure for organization of transportations. The evaluation of possible effects includes accounting for transportation costs, road conditions, traffic safety, and possible ecological and economical losses in case of emergency.

It is established that there are no efficient and at the same time universal ways to solve the routing problem. The universal disadvantage of all the approximation methods is analytically undefined accuracy of their performance. The known methods of transportation routing for small batches are oriented towards route distance minimization. The trip minimization criterion is not sufficient for the evaluation of road transport performance. Adoption of other criteria that change depending on the sequence of points in a route disputes the suitability of using the most known routing methods. Some attempts, undertaken in several works, to use the cost price criterion seem to be unsuccessful due to uncertainty of the procedure of vehicle load calculation on route.

The achieved research results of freight flows, characteristics and parameters of dangerous goods transportations allow solving the road network synthesis problem, verifying the adequacy of mathematical models, and substantiating the choice of transportation routing methods for specific operating conditions.

The results of the article can be introduced in the planning of dangerous goods transportations.

Forecast assumptions about the object of study substantiation of the staging of modernization of the dangerous goods transportation network in Ukraine.
