使用阻尼材料结构的试验模态分析

Experimental Model analysis of Structures with Damping Material

高分子聚合物做为阻尼材料的使用，使结构的模态分析出现特殊问题，本文介绍试验模态分析中的若干问题，包括模态阶次、模态参数的拟合、模态结构阻尼系数与粘性阻尼系数之间的关系。

This pape presents several problems on experimental modal analysis of a structure with high polymer damping material,such as model order,modal parameter fitting,the relation between modal structural damping coefficient and viso damping coefficient,sensitivity analysis and so on.
