滞后阻尼结构的自由界面试验模态综合与应用

THETECHNIQUEOF EXPERIMENTAL COMPONENT MODE SYNTHESIS WITH

针对试验模态综合，提出子结构剩余柔度函数的动态测试技术，通过实测频响函数分解出阻尼结构的各阶复剩余模态。在此基础上，发展了滞后阻尼结构的模态综合理论。最后，通过一典型梁的试验验证了该方法的合理性。

In this paper,aimed at experimental component mode synthesis (CMS),the technique of dynamic measurement of residual flexibility function for substructure was raised.Any order of the complex residual model for damping substructure could be separated from it by testing.Upon on the basis,the free interface CMS theory was developed for hysteretic damping structure.Finally,the rational character was proved by a typical beam′s testing.
