| 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。

| Abstract: | 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 |
