将广义模块化设计应用到液压机预应力机架的有限元分析中,提出了广义有限元模块和广义有限元模块接口的概念。阐述了ANSYS软件中有限元模块数据库的建立方法、有限元模块装配成整机分析模型的具体装配方法和预紧力载荷的模拟方法,用ANSYS参数化设计语言编制了组装有限元模块、预紧单元法施加预紧力和施加间隙导向约束的通用程序模块。最后以45 MN液压机预应力机架的有限元分析为例,详细说明了广义模块设计中分析环节的实施过程和此类液压机设计的注意事项,为同类机架的设计提供了参考和指导。

Generalized modular design was applied to finite element analysis of pre-stressed frame of hydraulic press.Concepts of generalized finite element modules and its interface were proposed.Methods of building database of finite element modules,assembling integrated finite element model from database and applying pretension load in ANSYS software were presented.Three program modules for assembling analysis model from generalized finite element module database,applying pretension loads and applying guide constraints were created with ANSYS parametric design language.At last,finite analysis of pre-stressed frame of 45MN hydraulic press was given as an example to present the process of generalized modular design,which could guide the design of similar press.
