摘要
基于弹性动力学变分原理,本文导出了混合型动力子结构方法的一种Ritz基矢量,即采用正交化的块Lanczos基代替主模态,结出了相应的子结构模态变换的格式和综合后的系统方程式.文未给出了算例.
Based on the variational principles in elastodynamics a kind of Ritz vectorsthat of orthogonalized Block-Lanczos bases was derived for hybrid dynamic substructural method in order to substitute the normal modes in substructures.The formulae of transforming matrix in substructures and the sythesized equa tions of motion were presented. Some examples were given at the end.
