摘　　要：基于自主研制的智能滚动接触疲劳试验装备,结合试验滑差率和试验载荷的精确控制要求,提出了主从同步控制滑差率控制方法和位移-载荷复合控制的载荷调控方法。以SIMOTION控制器为核心,设计了试验机的运动控制系统,并进行了试验验证。试验结果表明:滑差率平均控制误差为0.26%,满足±1%的控制精度要求;试验载荷平均控制误差为1.77%,满足±3%控制精度要求;试验载荷和滑差率的控制方法可行、有效,可为试验装备实现智能控制提供技术支撑。Based on the self-developed intelligent rolling contact fatigue test equipment,combined with the precise control requirements of test slip rate and test load,the control method of master-slave synchronous control slip rate and the load control method of displacements and loads composite control are put forward.In this paper,the motion control system of the testing machine is designed with the SIMOTION controller as the core,and the test results show that the average slip control error is 0.26%,which meets the control accuracy requirements of±1%.The average control error of the test load is 1.77%,which meets the control accuracy of±3%.The control method of test load and slip rate is feasible and effective,which provides a technical support for intelligent control of the test equipment.
