| 摘 要： | 试验数据和有限元数据相关分析修改有限元模型是工程界不断追求的技术,以解决模型简化存在的误差问题。目前存在着频率、振型、频响函数相关的几种方法,本文对试验数据和有限元分析数据相关的理论方法进行简要介绍,对CAE Calibrator软件的使用方法也进行了说明。并进行了某飞行器机翼的有限元模态计算和模态试验,着重用CAE Calibrator软件进行有限元分析模型与试验数据(频率和振型)相关性分析,修改了有限元模型,修改的设计变量合理,修改后的计算结果与试验结果(频率、振型)符合很好。

| Abstract: | Updating finite element models with test/analysis correlation is minimizing the test-analysis errors.There are several methods such as the frequency correlation,mode shape correlation and FRF correlation.The theory of test/analysis correlation is briefly introduced,and a correlation tool CAE Calibrator is introduced in this paper.Based on the modal test and normal modal analysis of a Delta Wing,the frequency correlation and mode shape correlation were performed.The analysis results of updated FEM match the test data well. |
