摘要：

针对伺服压力机控制环节上速度和转矩给定曲线的不足，对伺服曲柄压力机进行分析，根据伺服同步电机和曲柄压力机的数学模型，通过运动方程将二者结合在一起，并通过Matlab/Simulink平台进行联合仿真。考虑电机系统之间相互强耦合影响，给出电机在曲柄负载拉伸拔模运动模式下的实际和响应转矩、转速和三相电流仿真。以小型开式压力机参数为例，通过仿真分析得到伺服电机应达到的转矩、转速和三相电流图线。仿真分析结果表明，可以通过修改工艺曲线和参数获得特定情况下的转速、电流和转矩的实际曲线，有利于进一步完善伺服曲柄压力机矢量控制和成形工艺参数的优化。

For the weakness in speed and torque curves when controlling the servo crank press, the analysis on the servo crank press was carried on. Their working processes were combined and simulated with the Matlab/Simulink platform based on their digital models. Considering the mutual coupling effect of the motor system, the simulation of response torque, rotation speed and three-phase electric current were recorded in the working mode of crank load and tension draw. Taking the parameters of a small open press as an example, the graphs of torque, rotation speed and three-phase electric current were obtained by simulation analysis. It is showed that the actual curve of rotation speed, electric current and torque under specific conditions can be obtained by modifying the process curve and the parameters, and it also contributes to the further improvement of the vector control and the optimization of parameters in servo crank press process.
