摘　　要：通过对花键滚轧机液压系统工作原理的分析,达到研究数控滚压机的动态特性的目的,考虑负载特性,利用仿真软件AMESim建立了相应的液压模型并进行了动态仿真。结果表明,对由液压泵、液压缸、比例伺服阀组成的比例伺服阀控缸位置伺服系统而言,通过引入PID控制,并进行参数优化,可使得由液压缸驱动的负载位移得到精确控制,能很好地使加工的花键达到要求;使用AMESim软件的参数优化功能,可以减少参数调试的时间,所得到的最优参数能极大的提高负载的运动精度。By analysis working principle hydraulic system of the spline rolling machine, the servo_hydraulic proportional control system of the spline rolling machine was modeled and dynamic simulated by means of the software AMESim, consider the load characteristic, in order to study CNC rolling machine dynamic characteristic. The result shows that for valve-controlled cylinder position servo systems, by introducing PID and parameter optimization. So the requirement of the spline can be met during working. The adjusting time of the system parameters is shortened by means of the optimization function in AMESim,and the position accuracy of load is improved greatly by using the obtained optimized parameters.
