【Abstract】 In the design and test process of heavy-duty locomotives, the safety and stability of train operation is an important goal for the development of traction control systems for heavy-duty trains. In order to meet the needs of design and development personnel for the development of heavy-duty train traction control software, and to effectively reduce the development time and cost, this paper established a longitudinal dynamics simulation model of heavy-duty locomotive on Matlab/Simulink platform based on the longitudinal dynamics of the train. In order to verify the feasibility of the dynamic simulation model of heavy-duty locomotive established in this paper, the train was simulated and analyzed under different working conditions. The simulation results show that the train can be smoothly pulled and braked under different working conditions, which can meet the safety and stability of train operation, and provides reference for the actual line test or operation of heavy-duty locomotive.更多还原
