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(xì)積分法，解決了考慮多階模態(tài)的阻尼矩陣給求解所帶來(lái)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(yīng)用模態(tài)轉(zhuǎn)換來(lái)減小被修改模型的自由度數(shù)，模態(tài)轉(zhuǎn)換矩陣由數(shù)學(xué)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(guò)模態(tài)變換，利用振型向量與質(zhì)量陣和剛度陣的正交性，得到解耦的運(yùn)動(dòng)方程。先求出廣義激勵(lì)下各模態(tài)的響應(yīng)，然后疊加起來(lái)得到系統(tǒng)的總響應(yīng)。
