摘要：

为了对一种肘杆式伺服压力机教学实验平台机构进行静力学和动力学分析，通过解析法建立了机构的运动学模型、动态静力学模型和动力学模型。首先，应用复数矢量法推导出压力机实验平台机构的位置、速度和加速度求解方程，得到了机构的位置、速度和加速度；其次，应用达朗贝尔原理建立了压力机实验平台机构的动态静力学方程，求解了机构的平衡力和运动副约束反力；再次，建立了机构的拉格朗日动力学方程，求解了伺服电机通过滚珠丝杠对机构的驱动力；最后，分别利用Matlab理论计算与ADAMS虚拟样机仿真得到冲锤的位置曲线、速度曲线、加速度曲线，以及平衡力、运动副约束反力和驱动力的变化曲线，并验证了所建运动学模型、动态静力学模型和动力学模型的正确性。

In order to realize statics and dynamics analysis for a teaching experiment platform of toggle servo press mechanism, the kinematic model, kinetostatics model and dynamics model were established by analytical method respectively. Firstly, the solving equations of displacement, velocity and acceleration of experiment platform mechanism for toggle servo press were deduced by complex number vector method, and the displacement，velocity and acceleration of the above mechanisms were obtained. Secondly, the kinetostatics equation of experiment platform mechanism for toggle servo press was established by the D′Alembert principle, and the balance force and the constraint force of mechanism were solved. Thirdly, the dynamics equation of experiment platform mechanism for toggle servo press was established by the Lagrange method, the driving force of servo motor on the mechanism through ball screw was solved. Finally, the curves of hammer position, hammer velocity, hammer acceleration, balance force, constraint force of joints and driving force were obtained respectively by Matlab and ADAMS virtual simulation, and the correctness of kinematics model, kinetostatics model and dynamics model were verified.
