摘　　要：传统的变速器试验台惯量模拟用的是机械惯量盘,但是机械式惯量模拟有着机械结构复杂、安装调整困难等问题。文章从汽车行驶阻力入手分析变速器负载,通过电惯量模拟理论分析、异步电机矢量控制设计基于电惯量模拟的变速器试验台加载系统。基于MATLAB/simulink仿真平台对其模型进行仿真研究,结果表明使用异步电机进行惯量模拟,既可达到变速器试验台负载模拟要求,又能解决传统机械式惯量盘安装困难、不能无极惯量模拟的一些问题。The traditional transmission test-bed inertia simulation using the mechanical flywheel, but the mechanical structure of the flywheel is complicated and difficult for install. Therefore, this paper through analysis of the Transmission load with automobile driving resistance, and through the electrical inertia simulation theory and the vector control of asynchronous motor, to design the loading system of the transmission test bench. Based on MATLAB/simulink, the model of the electrical inertia loading system of the transmission test-bed is built. The results show that using asynchronous motor to simulate the inertia, can meet the requirements of transmission test-bed load simulation.
