摘要:

CATAS系统是用于全尺寸结构静力试验与分析的大型综合系统,目的之一就是为保证有限元分析和工程细节分析结果和试验测量结果的一致性和可靠性。对设计厂、所提供的强度校核的有限元模型如何修改后建立用于试验分析的有限元模型进行了论述。

关键词: 有限元建模, 模型修改, 结构分析

Abstract:

CATAS ( Computer Aided Test and Analysis System ) is used for combining large scale static structural test and analysis. One of its aims is ensuring the consistency and reliability between structural analysis results ( FEM or engineering method ) and test measuring data. How to modify test based FEM models from the one used for designing is demonstrated.

Key words: FEM modeling, modification of FEM models, structural analysis
