阻尼材料动态阻尼系数的测定

摘要

Using the same damping materials,the determined damping coefficient of the specimens with different size have a big difference.This paper presented the effect of frequency on the damping coefficient and discussed the determination method of dynamic damping coefficient.So that the determined results of different specimens prepared with the same damping materials are unified.%相同的阻尼材料，采用不同尺寸的测试试件测定的阻尼系数存在很大的差异。本文提出了频率对阻尼系数的影响，探讨了动态阻尼系数的测试方法，将相同阻尼材料、不同试件测定的结果统一起来。
