摘要：

针对伺服机械压力机双动肘杆机构双自由度的特点，采用逆推设计原理对双动肘杆机构的主肘杆系统进行解耦，以滑块下死点作为起点进行设计分析，利用矢量方程解析法与动态静力学方法建立机构运动学与动力学的数学计算模型；采用MATLAB软件优化工具箱对主肘杆系统的运动学与动力学的多目标函数进行优化，得到了满足公称压力行程滑块速度波动小以及所需机构驱动扭矩小的一组参数；采用ADAMS软件对已有的等长肘杆机构、三角肘杆机构以及双动肘杆机构进行建模仿真，并对滑块的运动状态以及曲柄所需扭矩情况进行对比分析，得出双动肘杆机构符合伺服压力机设计要求。

For the characteristics of two degrees of freedom for servo mechanical press with dual-drive toggle mechanism and, the main toggle system of dual-drive toggle mechanism was decoupled by backward induction design principle, and the design analysis of adopting the bottom center of slide as the starting point was conducted. Then, the mathematics computing model of kinematics and dynamics was built by vector equation analytic method and dynamic statics method. Furthermore, the multi-objective function of kinematics and dynamics of main toggle system was optimized by MATLAB′s optimization toolbox, and a set of parameters which meet the demands of small speed fluctuation and low driving torque of slider was obtained. Finally, the existing isometric toggle mechanism, triangle toggle mechanism and dual-drive toggle mechanism were simulated by software ADAMS, and the working condition of slider and torque needed by crank were compared and analyzed. The conclusion shows that the dual-drive toggle mechanism satisfies the requirements of servo press.
