本文在文献[1]的基础上,将子结构缩减阻抗综合法推广应用于任意复杂结构的受迫振动,并提出了结构综合阻抗矩阵的再缩减,从而把求解方程的阶数进一步聚缩到等于结构激励域的自由度数这一最小尺度。与此同时。本文还编制了一个计算结构动力响应的通用程序;在模型上的计算结果与实验结果吻合很好。
On the basis of [1], this paper generalizes the substructure reduction impedance synthesis method to the forced vibration of arbitrarily complex structures, and proposes a further reduction of the structural impedance matrix so that the order of the solution equation is further condensed to Equal to the minimum dimension of the number of degrees of freedom of the structural excitation domain. at the same time. This paper also compiles a general program to calculate the structural dynamic response; the calculated results on the model are in good agreement with the experimental results.
