摘要
有限元法是一种工程近似求解的方法 ,存在误差 ,所以在用有限元软件进行工程分析计算时 ,很重要的一点是分析过程中必须审视分析的结果 ,对结果有正确的认识 ,从而指导工程分析的正确进行。采用有效的方法对有限元分析结果的准确度进行估测 ,是十分必要的。举例说明了用公式法和模态分析法对有限元分析结果准确度的判定 。
Finite element method(FEM)is an approximate solution in engineering,there exists some error in the analysis result,so it is important to check the result and to geta right view of the result in the analyzing process,then this can lead the right analysis in the next step.Applying effective measure to evaluate the veracity of FEA result is quite necessary.This article illustrates the judgement of veracity of the FEA result using the methods of both formula and mode analysis through examples,and gives some correlative method based on experience.
