首先引入了动力相似非耦联系统和方程的概念。应用加权余量法于动力相似非耦联方程，建立了结构实验的动力模拟势能原理。对该势能原理应用拉氏乘子法，建立了广义动力模拟势能原理。最后，用动力模拟势能原理对矩形板进行了动力模拟计算。
Firstly, the concept of dynamic similar uncoupled systems and equations is introduced. Applying the weighted residual method to the dynamic similar uncoupled equations, the dynamic simulation potential principle of structure experiment is established. Applying Lagrange multiplier method to the principle of potential energy, the principle of generalized dynamic simulation potential is established. Finally, the dynamic simulation of the rectangular plate is carried out with the principle of dynamic simulation of potential energy.
