modal transformation

基本解释

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.
采用了模态变换和精细积分法，解决了考虑多阶模态的阻尼矩阵给求解所带来的困难。
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.
应用模态转换来减小被修改模型的自由度数，模态转换矩阵由数学模型的低阶模态组成，高阶模态的静力修改被考虑。
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.
通过模态变换，利用振型向量与质量阵和刚度阵的正交性，得到解耦的运动方程。先求出广义激励下各模态的响应，然后叠加起来得到系统的总响应。
