本文建立了一种“利用约束结构试验获取自由结构试验模态的伽略金法”(简称GMTCF)。同时指出了进一步发展GMTCF的几种途径。算例表明,本文GMTCF是可行的,并能直接应用于某些实际工程问题。
In this paper, we establish a “Galerkin method to obtain free-form test modalities using constrained structure tests” (GMTCF). At the same time, several ways to further develop GMTCF are pointed out. The example shows that this article GMTCF is feasible and can be directly applied to some practical engineering problems.
