摘要
阐述了Cosmos/M有限元分析软件的理论基础,推出了子结构法在大型有限元模型的线性静力分析和抛物线性四面体实体单元中的三维正交应力一应变的关系式,通过在长距离带式输送机机架零件的静力分析中子结构法的应用,证明其在微机上求解大型有限元模型是可行的,为在微机上求解大型有限元模型提供了一种有效的方法。
The paper introduces the theoretical background of cosmos/M finite element analysis software and concludes the equations of the three-dimensional orthogonal stress-strain relations of the parabolic tetrahedral elements applying minor structure method in linear static analysis of large finite element model. The practice proves that the minor structure method is feasible and effective to solve the large finite element model with mirocomper.
