Stability analysis of transport vehicles dynamics by the aid of evolutional programming and Lyapunov first method

Keywords:

O.N. Karpechenkova


The paper presents a description of the algorithm for optimizing of dynamical characteristics of elements and nodes of a kinematic diagram of a railway vehicle based on the biological evolutionary model and random search methods. An example of a genetic algorithm to study the vertical oscillations of a passenger car on bogies КВЗ-ЦНИИ is considered. The problem of optimizing the values of dynamic parameters having been solved it became possible to significantly increase the margin of stability and crew safety. The above algorithm and its implementations can be used in the development of technologies to improve complex transport systems. The first Lyapunov method is used to study railway vehicle motion stability.
