摘　　要：为处理虚材料结构试验模态,作者曾建立过一种广义伽略金法,在该广义伽略金法的基础上,演变出一种动柔度基向量组合法。它除了可以用于本文命题的领域外,同时像现有静柔度基向量组合法一样,还可以有效地用于特征值重分析工作。数值表明,动柔度基向量组合法非常有效。The author had established a generalized Galerkin method for test modal processing of pseudomaterial structure. In this paper, dynamic flexibility-based vector combination method was derived on the basis of generalized Galerkin method. Dynamic flexibility-based vector combination method, which in addition can be used for this proposition field, can also be used effectively to eigenvalue re-analysis. The numerical results indicate that dynamic flexibility-based vector combination method is very effective
