第五讲结构参数识别一用试验数据修改分析模型结构动力学的理论分析方法已经被许多人研究,并且已经有了很多很好的计算程序供人们使用,同时,结构动力学的试验方法也日趋成熟。然而结构的分析和试验之间存在着一定的距离,这主要是分析过程中的种种假定造成的。这就有必要来研究试验和分析之间关系,当前主要是研究怎样用试验数据修改分析模型。这方面的问题随着结构的大型化和复杂化而日益迫切。它在预
Lecture 5 Identification of structural parameters - Modification of analytical model with experimental data The theoretical analysis of structural dynamics has been studied by many people and many good computational procedures have been put in place for people to use. At the same time, the test methods of structural dynamics are becoming increasingly popular mature. However, there is a certain distance between structural analysis and testing, which is mainly caused by various assumptions in the analysis process. This is necessary to study the relationship between testing and analysis, the current study is mainly how to use experimental data to modify the analysis model. The problems in this area are increasingly pressing with the increase in size and sophistication of structures. It is in advance
