Abstract

Boldyrev A.P., Keglin B.G., Fatkov E.A., Shljushenkov A.P. Historical aspects of creation and development of faculty Dynamics and strength of machines . The article describes history of creation of speciality and department Dynamics and strength of machines. Article shows the main stages of development of department, founders and teachers of speciality.

Keglin B.G., Aldjuhova N.V., Aldjuhov V.A. Linearization dynamic systems with nonlinear elements. The algorithm of the decision of a problem about fluctuations of nonlinear systems in fre-quency area for a case when the model contains set of nonlinear elements is considered. Factors - for of some nonlinear characteristics with use of various criteria are certain. The deci-sion of a problemon movement of the freight car on roughnesses of a rail way is considered. Com-parison of the received results with the decision in time area a method of numerical integration of the equations of movement is executed. Conditions of application of a method are revealed.

Fatkov E.A. Estimation power loading absorbing device avtocoupling. Results of calculations power loading various absorbing devices in conditions of real operation of the freight car are result-ed. The quantitative estimation of the energy perceived for year is received.

B.G.Keglin, A.P.Boldyrev, A.P.Shljushenkov, E.A.Fatkov, I.N.Evtjuhov. Development and re-search of the hydropolymeric absorbing device avtocoupling. The design of the new hydropoly-meric absorbing device GP-120 is presented. Results are resulted is settlement-experimental researches the absorbing device.

A.P. Boldyrev, JU.V. Abel, M.N. Levaia, A.M. Gurov. Research of job hydropolymeric ab-sorbing the device with autoadjustable valve system. Results of theoretical researches of the hy-dropolymeric absorbing device are resulted. The mathematical model of device GP-120A is devel-oped, parameters of the hydraulic valve are optimized. Comparison of characteristics of various up-datings of devices is spent.

B.G. Keglin, E.G. Gajvoronsky. Application of method Runge-Kutta with alignment for the decision of problems of frictional self-oscillations in the distributed systems. In the work is de-scribed variant of the method Runge-Kutty tailored for decision of the problems of friction auto-oscillations with stop. They are shown difficulties of the syntheses of the fitting method and the nu-merical decision of the differential equations with variable structure. It is brought a quantitative es-timation of advantage the given method in contrast with the classical method Runge-Kutty at the study friction auto-oscillation processes in systems with distributed parameters.

B.G. Keglin, E.G. Gajvoronsky. Features of course of process relaxational self-oscillations in the distributed systems. The article describes the results of examinations in qualitative comparison of processes of frictional auto-oscillations in concentrated and continuum systems. The presence auto-wave and stochastic processes in auto-oscillating systems with distributed parameters in the presence of a dry friction is shown.

Boldyrev A.P., Gurov A.M., Fatkov E.A. The basic tendencies of cargo transportations railway transportation of Russia. The analysis of statistical data RRR on cargo transportations is spent. The spectrum of weights of freight cars is received. Comparison with earlier received distributions is spent.

A.A. Halaev, E.N. Titenkova. Methods of the Estimation of the vat of polymeric elastic elements of perspective absorbing device avtocoupling GP-120. Models of hyperelastic materials are considered. The estimation of various kinds of experiments for polymeric samples is lead.

N.N. Lysikov, A.P. Shljushenkov. Modeling loading of the frame of the carriage of shunting diesel locomotive TEM21. Substantive provisions of a technique of research operational loading the designs, based on use of means of computer modeling of dynamics of systems of bodies and program complexes of the certainly - element analysis of the VAT are resulted at static loading. The sequence of calculation is illustrated by the example of the analysis operational loading and fatigue durability of a frame of the carriage of a shunting diesel locomotive.

Senushenkov M.A., Shvachko S.N. Mathematical modeling of stress-deformed condition of re-inforced-concrete reservoirs to the program AXIS-Lq 2.1. In this article the method of analysis of stress-deformed condition of reinforced-concrete reservoirs with the usage of the axisimmetrical calculation schemes according to the program AXIS-Lq 2.1 for the reservoir with the capacity of 30000 m3 as an example is examined. The most dangerous sectors of the construction are revealed and the offers for the increase of quantity of steel in this sectors are given. The minimum level of the residual pre-stress of the circular armature is defined.
