摘要
本文提供了在实验模态分析中消除附加质量、刚度和阻尼对复模态参数影响的方法。此外,作者将上述方法予以发展,使它适用于阻尼结构修改后的振动再分析,文中附有数字例题,其结果表明了方法的有效性。
This paper presents a method to eliminate the effects of additive masses, stiffnesses and dampings on the complex modal parameters in experimental modal analysis. At the same time, in order to make the method adjust to vibration reanalysis of structural modification the method is developed. The results of the example show the method is available.
