摘　　要：建立了PWS-100型电液伺服动静万能试验机系统的传递函数模型,对系统进行仿真分析,通过画出系统的开环Bode图、闭环Bode图及系统的阶跃响应曲线,分析了系统的频率特性、稳定性及系统性能的影响因素。分析结论符合工程实际,对试验机的设计和使用有一定的指导意义。The transfer function model of the PWS-100 dymamic & static universal testing machine with electro-hydraulic servo controlled is created. Simulation of the system is studied by drawing the open-loop bode diagram,closed-loop bode diagram and step response curve. The influence factor on frequency character ,steady and performance of the system is also analyzed.The research results are coincide with practical application in engineering and are significant in designing and using of the testing machine.
