Influence of electrical part of traction transmission on dynamic characteristics of railway vehicles based on electromechanical coupling model

Abstract With the continuous development of rail transit industry and the acceleration of train speed, higher requirements are established for the operation quality of high-speed trains and the reliability of transmission system. In the process of train running, speed fluctuation and vibrations from...
