【Abstract】 Aiming at the problem that traction adhesion control algorithm of electric locomotive is difficult to verify in the process of research and development, starting from the basic principle of adhesion, the overall framework of adhesion control model is designed, and the mathematical models of wheel set dynamics model, vehicle body dynamics model, train resistance model, axle load transfer model and creep force calculation model are established, a hardware in the loop simulation platform composed of traction control unit and realtime simulator is established. The test results show that the semi-physical simulation model and the simulation method introduced in this paper can effectively achieve the purpose of testing and verifying the adhesion control algorithm of electric locomotive.更多还原
