modal transformation

基本解釋

To overcome the difficulties in the solving process brought by the multi-modal damping model, the modal transformation strategy and the precise time-integration method are applied.
采用了模態(tài)變換和精細積分法，解決了考慮多階模態(tài)的阻尼矩陣給求解所帶來的困難。
In modal transformation only the modes associated with the lower eigenfrequencies of the mathematical model are used and the static corrections of the higher modes taken into accout.
應用模態(tài)轉換來減小被修改模型的自由度數(shù)，模態(tài)轉換矩陣由數(shù)學模型的低階模態(tài)組成，高階模態(tài)的靜力修改被考慮。
Uncoupled differential equations of motion were obtained by utilizing the modal transformation and the orthogonality of the mode shapes with respect to the mass and stiffness matrices.
通過模態(tài)變換，利用振型向量與質量陣和剛度陣的正交性，得到解耦的運動方程。先求出廣義激勵下各模態(tài)的響應，然后疊加起來得到系統(tǒng)的總響應。
