    摘要:

    为了提高拉床性能和拉削质量,根据电液比例伺服阀特点设计了应用电液比例伺服阀控容积调速的卧式拉床主回路。通过电液比例伺服阀控容积调速方式实现对拉削速度的控制。以拉削速度为反馈量形成闭环控制,抑制拉削过程中刀具跳动。应用AMESim软件建立了拉床液压系统仿真模型,通过仿真分析验证该系统能有效提高拉削过程的平稳性。对调速系统控制参数进行优化,取得了良好的仿真结果。研究结论为电液比例伺服阀控容积调速系统在液压拉床上的应用提供了参考。

    Abstract:

    To improve the performance and broaching quality of broaching machine,according to the characteristics of electrohydraulic proportional servo valve, the major loop of horizontal broaching machine was designed based on the electro-hydraulic proportional servo valve volumetric speed control system. Through the way of electrohydraulic proportional servo valve volumetric speed control mode, the control to broaching speed was realized. A closed loop control was formed using broaching speed as feedback,to inhibit the impacting in broaching process. The simulation model of the broaching machine hydraulic system was established by using AMESim software. Through simulation, it is verified that the system can effectively improve the stationarity of broaching process. The parameters of speed control system were optimized and the good simulation results were obtained. The results provide reference for application of the electrohydraulic proportional servo valve controlled volumetric speed control system in hydraulic broaching machine.
