摘　　要：根据高铁轴承试验台的结构形式和性能指标,确定高铁轴承试验台液压伺服加载的总体方案,建立其动力机构的负载流量方程和负载压力方程,并对其控制系统进行分析和建立其数学模型。然后,推导出液压伺服控制系统的传递函数,再利用Matlab软件对其控制系统进行动态仿真,并加入PID环节进行系统校正。最终设计出稳定性、快速性和准确性都符合要求的高铁轴承试验台的液压伺服加载系统。According to the structure form and performance index of high-speed railway bearing test-bed,the test-bed servo hydraulic loading plan was determined,and the load pressure and load flow equation for symmetric dynamic mechanism was established.The valve controlling cylinder system was theoretically analyzed,and the mathematical model was established.Then the output pressure load transfer function was deduced.Finally,by using Matlab to make the dynamic simulation and correcting the system with the PID,the hydraulic loading system was designed which can meet the requirements.
