摘要
大型计算软件提供的丰富单元类型为仿真计算带来了极大便利,而如何选取合适的单元类型是保证仿真精度的关键要素之一。选用ABAQUS软件中常用的几种实体单元类型,以某公司无轨电车上拉杆产品为研究对象,对其进行有限元网格划分,分析其结构静强度,并对比研究计算结果以发现相关规律。通过实例计算比较了不同单元类型对计算结果精度的影响,并为有限元分析建模过程中单元类型的选取提出一些建议。
The rich cell types provided by large-scale computing software provide convenience for computing.How to select the appropriate element type is one of the key elements to ensure the simulation accuracy.In this paper,several solid element types commonly used in ABAQUS software are selected,and the trolley car upper tie rod products of a company are taken as the research object.The finite element mesh is divided,the structural static strength analysis is carried out,and the calculation results are compared.The effects of different element types on the accuracy of calculation results are compared through example calculation,and some suggestions on the selection of element types in the process of finite element analysis and modeling are put forward.
