Abstract

The paper develops methods of system analysis and technologies for control dynamic conditions of technical means of railway transport. Methods of structural mathematical modeling are used, within the framework of which the design scheme of the object, considered as a mechanical oscillatory system with several degrees of freedom, is interpreted as a dynamically equivalent automatic control system. The problems of the dynamics of the coupling of two freight railway carriages with two variants of its rigidity (conventional and rigid hinge-type fastening) are considered. It is shown that with a certain choice of the values of the moments of inertia of the railway carriages and the parameters of the location of the center of mass, it is possible to solve the problems of motion stabilization. Concepts are proposed for the experimental determination of the moment of inertia and coordinates of the center of mass of the railway carriage when rolling the cars off the marshalling hump and passing a special measuring station. Algorithms for determining the values of the parameters of the center of mass of the railway carriage and the values of the moment of inertia are proposed.
