摘　　要：为检测加固的桥面板的疲劳寿命,设计以电液伺服系统为核心的桥面板加固疲劳试验系统。采用电液伺服技术实现主机设计,结合PID+F调节控制算法,解决大型试件在进行动态疲劳试验时因材料性能变化而造成的控制不稳定性。试验系统采用WinPWS测控软件,实现无人值班自动存储数据,控制模式实现平滑无扰切换。该系统已经成功应用于工业测试,具有抗干扰能力强,动、静态控制性能稳定等优点。In order to detect the fatigue life of bridge reinforcement panel,we design a fatigue testing system with a electro-hydraulic servo system as the central device.The host controller designed by electro-hydraulic servo technology,combining with the PID+F adjust-control algorithm,solves the instability of large specimens due to the changes of material properties during dynamic fatigue test.Using WinPWs monitoring and control software,the system can store data unattended automatically and switch the control mode smoothly.The system has been successfully used in industrial testing,with advantages of strong anti-jamming capability,dynamic and static control,and stable performance.
