用试验识别模态修改数学模型方法与复杂结构建模技术

THE MODIFICATION METHOD OF MATHEMATICAL MODEL USING MEASURED MODAL PARAMETERS AND DYNAMIC MODELING TECHNIQUE OF COMPLEX STRUCTURE

本文通过理论建模与试验建模技术的回顾，介绍了理论与试验相结合的建模技术，提出用试验识别的模态修改数学模型的新方法，用一个典型例子说明这种方法的应用，并且提出大型复杂结构建模的新技术──子结构试验模型综合法。

Abstract In this paper,the modeling method of combining theoretical analysis and test is developed, the modification method of mathematical model using measured modal parameters is presented. These present methods are used as the dynamic modeling technique of large complex structure.
