Mathematical Modeling of Non-stationary Processes During Train Movement

At present, during the modeling traction units of railway transport, the most widely used models, where traction electric drive is represented by a single mass system, and the possibility of non-stationary modes of its operation are neglected. This approach makes it impossible to evaluate objectively the transition processes during the acceleration and deceleration of the train. In view of this, the article develops a mathematical model of the train, which takes into account the specificity of the work of the mechanical part of the traction drive and allows us to evaluate the influence of boxing and skidding on the dynamics of train movement.
