摘要
模态综合法是计算大型复杂结构动态参数十分有效的方法。在现有方法的基础上,提出了一种基于同一类完备李兹向量空间的实用完备模态空间作为李兹分析的基向量空间,并将它应用到滞后阻尼结构中,建立了一种精确的混合界面复模态综合法。这种方法比使用"剩余柔度"描述的子结构位移更加精确,且可以获得全结构的模态。
The modal synthesis method is a more effective method for calculating dynamic parameters of large complicated structure. By the existing method, a kind of vector space which based on the same kind Ritz vector space in Ritz analysis is given. The vector is applied in the hysteretic damp structure, and the accurate mixed interface complex modal synthesis method is derived. This method can obtain the more accurate sub-structural displacement and whole structural modes.
