有限元模型修正中处理不完备实测模态参数的方法研究
The study on dealing with incomplete experimental modal parameters during the finite element model updating
摘要
Abstract
T his paper first introduces the basic theoretical contents of real and complex mode parameters. Secondly, it introduces the recognizing and evaluating methods related to experimental modal parameters. Then, it indicates two kinds of important technology widely applied to deal with incomplete experimental modal parameters, that is model reduction technology and expansion technology, and reveals the interrela‐tionship between them .Finally, it introduces a method which is not applied widely but with a certain theo‐retical value in dealing with incomplete experimental modal parameters .关键词
