将伺服驱动技术应用于压边力控制，可以更有效地控制拉深成形过程，提高成形效果。采用伺服电机驱动的压边力控制系统由机械和数控系统两部分组成，系统参数匹配的合理性对压边力控制的动态性能影响较大，而系统的动态性能直接影响到压边力控制精度和效果。首先对双滑块六杆机构输入输出方程进行了线性化处理，建立了机械系统、数控伺服系统的数学模型，得到了压边力控制系统的数学模型和仿真模型，对控制系统进行了仿真分析，初步确定了控制系统的位置环 PID 参数。最后根据仿真分析结果进行了压边力控制实验系统的参数设定，实验表明，根据仿真值稍作调整就能达到实验系统的控制要求，大大缩短了系统调试时间。

Servo-driven control technology of BHF is more effective and can improve the forming effect in deep drawing process.BHF control system driven by servo motor was composed of the me-chanical system and CNC system.The parameters of components in BHF system had a greater influ-ence on the dynamic performance of the system,so it could have effects on accuracy and efficiency in BHF control.Firstly linearization of the input and output equations was made for the six-bar linkage and the double-slider mechanism.And mathematical models of mechanical system and CNC control system were obtained respectively.Then performance of the system was simulated and analyzed and the PID parameters of the position loop were adj usted.Finally,the parameters in the experiments of the BHF control system were given based on simulation results.The experimental results show that it can meet the requirements of the BHF control to adjust slightly the values of the parameters of the control components based on the modeling and simulation results,so the debug time of system control parameters can be shorten greatly.
