Design and Analysis of Mechanical Press Experimental Platform

机械压力机因其结构可靠、操作简便、生产效率高等优势被广泛应用。本文参照国内现有相关型号精密压力机,设计了一种传统机械压力机实验平台。首先,通过对机构的初始参数和运行方式进行分析,绘制机构运动简图,利用Soildworks建立整体的三维模型,通过Adams进行运动学和动力学仿真。然后,利用Ansys Workbench对机身机体、低速轴,连杆进行有限元分析。最后,对机身进行拓扑优化,求得机身最优解,重新建立机身模型,对新建模型进行静力学分析和模态分析,验证优化结构合理性。

Mechanical presses are widely used due to their reliable structure, easy operation and high pro-duction efficiency. In this paper, a traditional mechanical press experimental platform is designed with reference to the existing domestic model precision presses. First, by analyzing the initial pa-rameters and operating modes of the mechanism, a schematic diagram of the motion of the mech-anism is drawn. The overall 3D model was built using Soildworks and kinematics and dynamics simulations were performed by Adams. Then, use Ansys Workbench to perform finite element anal-ysis on the frame body, low speed shaft and connecting rod. Finally, the topology of the fuselage is optimized, the optimal solution of the rack is obtained, the rack model is re-established, static analysis and modal analysis are performed on the new model, and the rationality of the optimized structure is verified.
