摘要
在轨道牵引系统研究中,真车试验有着成本高、周期长、实现困难等诸多缺点,而搭建轨道车辆牵引电机负载模拟平台就可弥补这些缺点。本文提出了搭建交流电机——直流电机负载模拟平台的方法,推导出了牵引电机轴上的等效负载转矩及等效负载惯量,并基于高速动车组CRH2搭建了负载模拟平台Matlab/Simulink仿真模型。
On the study of railway traction system, real vehicle test is not convenience due to its high cost, long test cycle and other defects, while load emulation is easy to realize. This paper proposes a method of load emulation by creating AC motor--DC motor drive platform, derives the equivalent load moment and inertia on traction motor, completes the simulation of the platform using Matlab / Simulink based on CRH2.
