摘　　要：模锻压机主工作缸柱塞和活动横梁的连接方式的合理选择是压机设计中的重要环节。基于MSC.MARC仿真平台,对单球铰和双球铰两种不同的连接方式分别建立六面体模型,根据实际工况模拟压机偏载过程,得出偏载时不同连接方式下主工作缸系统的应力分布和变形程度,并与理论计算相验证,证明仿真模型的可靠性,为主工作缸的设计提供参考,同时,为活动横梁以及整机的有限元分析提供边界条件。A reasonable connection between the press plunger and moving beam is very important in the design of large-scale stamp forging hydrostatic press. Establishing FEA models of single sphere connection and double spheres connection and simulating the process according to the actual production on the platform of MSC. MARC, then, the stress and the deformation of the whole system can be obtained. At the same time, the force which the press plunger acted on can be got from the result, the force is a highly important parameter for the credibility of the forging press. Provide reference with the design of the main cylinder, mean-while,it can also offer boundary conditions for the simulation of the movinz beam and the forging Dress.
