摘要
本文提出了弹性-粘弹性复合结构动力特性和动力响应的数值计算方法。为了给动力特性分析提供初值,定义了复合结构的“对偶保守结构”概念。用“对偶保守结构”的实模态参数确定复特征值初值,逐个迭代计算复合结构的复模态参数,同时还给出了两种数值方法计算复合结构的时域响应,可适应于一般载荷的响应计算,最后给出了部分计算与实验结果,并进行了比较,结果令人满意。
In this paper one suggest computational methods for dynamic behavior and response of the composite structures which consist of elastic and viscoelastic materials. First the concept of 'corresponding conservative structure' of the composite structure is defined,And it is used to offer starting values of complex eigenvalues of the composite structure so as to solve the eigenproblem by a special iteration method. Two numerical methods are introduced for time-domain response calculation. Finally computational and experimental results of a sample problem are listed and compared.
