为解决传统离合器性能试验系统中机械惯性飞轮组重量大、调整困难及存在惯量级差等问题，将机械惯量电模拟技术引入离合器试验系统。通过分析汽车行驶过程中受力情况，建立了离合器动力学模型，并结合离合器试验系统特点，提出了转矩反馈转速闭环控制的机械惯量电模拟控制方法，并在离合器试验系统中实现，与传统机械惯性飞轮组模拟的不同路况条件下离合器起步对比试验。试验结果表明：该控制方法能够较为准确地模拟离合器起步过程中转速、转矩变化特点。
In order to solve the problems about heavy, difficult to adjust, discontinuous inertia rank of mechanical inertia flywheels in the traditional clutch performance test system, the technology of electric emulation for mechanical inertia is introduced to clutch test system. Through analyzing loads on moving automobile, the dynamic model of clutch was developed and combined with the characteristics of clutch test system, the torque feedback and speed closed-loop control method of electric emulation for mechanical inertia was proposed. In contrast to clutch drive away test based on the traditional mechanical inertia flywheels, the result indicates that the control method can accurately simulate the change characteristics of torque and speed of clutch in automobile start
