摘　　要：本文根据粘弹性理论,针对复合材料的各向异性,受横向剪切变形影响大以及比重轻等特点,构造了利用测试单粘弹性参数结构复频率的方法,识别得到复合材料等效动态性能参数的复频率.In this paper, a complex ferquency method based on the theory of viscoelasticity for identifying the parameters describing effective dynamic behavior of composite materials ispresented. In this method, some properties of composite materials, such as nonisotropis, influence of shearing deformation and low density, are considered.
