摘　　要：介绍了压曲机液压回转工作台定位系统要求及组成,并计算确定了回转台最高运行速度,得到运行一个工位所用时间与其最高转速之间的关系曲线图。建立AMESim液压仿真模型,对开环控制与带PID控制器的闭环控制进行比较,最终确定采用PID控制来有效克服了负载扰动对转台定位精度的影响。The requirement and composition of the positioning system for the hydraulic rotary table of the bending machine are introduced.The maximum operating speed of the rotary table is calculated and determined.A relationship graph between the table running in one station time and the maximum speed is plotted.After the hydraulic simulation model established by AMESim,the effect of using the open-loop control and that of using the closed-loop control with the PID controller are compared.The result shows that using the PID control can effectively overcome the effect of load disturbance to the positioning accuracy of the rotary table.
