摘要
依据广义模块化设计原理,在ANSYS中分别建立了45 MN锻压机预紧组合机架各个功能模块的有限元模型,采用MPC绑定接触模拟闭合模块间的连接,标准接触模拟可开裂模块间的连接,分别讨论了空载和临界载荷两种状态下机架的变形和应力分布,计算方法和计算结果为此类机架的分析、设计提供参考和指导.
According to generalized modular design, finite element models of each function module are built in ANSYS, which belong to pre-tightening frame of 45 MN forging press. MPC banded contact is used to simulate the connection of two fixed parts,while standard contact is used to simulate the connection of two dissoeiable parts. Deformations and stresses of the forging press under two working conditions are discussed.which provide good guides to the design of such kind of press.
