摘要
疲劳试验机是疲劳测试中最常用的设备。根据材料疲劳试验机的工作原理,建立电液力伺服系统的数学模型。利用MATLAB软件中的SMULINK构建了仿真模型,获得了反映系统性能的仿真曲线。为材料疲劳试验机控制系统的改进提供了理论依据。
The fatigue testing machine is the most popular device in testing fatigue capacity of material. According to the working principle, the mathematic model of electro-hydraulic force servo system was built, and the simulation model of this system was built by SIMULINK of the MATLAB. The simulation curves that reflect the system performance was achieved, and the theoretical basis for improving the control system of material fatigue testing machine was put forward.
