机械结构动力学模型修正技术的现状与发展

摘要

In this paper,basic philosophies and critical technologies of model updating in structural dynamics are reviewed,and the applications of model updating in the field of engineering,such as structural dynamics modification,hybrid modeling,model verification and validation,load identification,structure condition assessment and damage identification,are discussed simultaneously.In light of the difficulties of model updating in engineering applications,the research focus of the present structure model updating and trends of model updating technology are also probed.%在回顾结构动力学模型修正基本问题及关键技术的同时,论述模型修正在工程领域的结构动力修改、混合建模、模型确认、载荷识别、结构状态监测及损伤评估等方面的典型应用状况。针对模型修正技术在工程应用方面遇到的困难,还探讨了当前结构模型修正的研究热点以及模型修正技术的发展趋势。
