摘要
采用悬臂梁横向弯曲自由振动方法，研究了单向增强ＶＩＲＡＬＬ（ｖｉｎｙｌｏｎｒｅｉｎｆｏｒｃｅｄａｌｕｍｉｎｕｍｌａｍｉｎａｔｅｓ）复合板及相应的单一铝合金板的振动阻尼性能．结果表明，前者的振动衰减系数高于后者．还发现ＶＩＲＡＬＬ复合板的阻尼性能受其纤维取向影响．
Trans-flexural free vibration tests of the cantilever beam have been used for studying the vibration damping characteristics of unidirectionally reinforced VIRALL (vinylon reinforced aluminum laminates) and the corresponding monolithic aluminum alloy plate. The results show that the former has higher vibration decay coefficient than the latter.It is also found that the vibration damping properties of VIRALL laminates are influenced by the fiber orientation in it.
