子结构经粘弹阻尼连接后系统动特性的预测

为有效地预测子结构经粘弹阻尼连接后新系统的动特性,本文基于重分析原理,提出了一个预测的新方法,还发展了一种为求解新特征方程的粘弹连接量与特征值同时迭代法。最后,算例表明文中提出的方法正确、有效。

Prediction of Dynamic Properties of the Substructure Systems Connected by Viscoelastic Damping

In order to e~fectively predict the dynamic characteristics of the substructure systems connected by viscoelastic damp~ng~ a ne~, method for predicting is preseated based oft the principle of rcanalysis. At the same time~ an iterat~rc algorithm for complex ciger~values with the viscoelastic connection amount is still developed. Lastly~ an example computed shows that the method presented in the paper is correct and cffecti'~e.
