摘要: 为了提高电动负载模拟器的加载性能，根据电动负载模拟器的系统构成，建立其相应的数学模型，分析系统刚度和负载惯量对多余力矩、系统稳定性和响应速度这3个方面的影响，分析和确定了系统的最佳刚度和负载惯量，利用MATLAB软件对结果进行仿真验证；仿真结果表明：加载后的正弦曲线能够较好的复现，且响应速度快、稳定性好；设计电动负载模拟器最佳的刚度和负载惯量的时候，不仅要考虑到对多余力矩的抑制，还要考虑到系统的稳定性和响应的快速性。Abstract: To improve the load performance of the electric load simulator, the corresponding mathematical model was established according to the system configuration of the electric load simulator, The influence of stiffness and load inertia of the system for the surplus torque, the system stability and the response speed was analyzed, so as to analyze and define the optimal stiffness and load inertia. The simulation results were verified by MATLAB software. The simulation results showed that the sinusoidal curve could be reproduced well, the response speed was fast and the stability was good, and it is necessary to consider not only the suppression of surplus torque, but also the stability of the system and the rapid response when designing the optimal stiffness and load inertia of the electric load simulator.
