| 摘 要： | 应用模态综合法，具体分析了由三个子结构所组成的系统。首先将各子结构的运动方程用该子结构的模态坐标表示出来，在模态空间内作自由度减缩。然后根据边界条件将各子结构联系起来，综合得到整个系统的运动方程，从而大大减少了系统的自由度数。

| Abstract: | This paper analyzes a system consisting of three substructures by means Of modes synthesis method. First, analyze each subsmicture using modal analysis method to g6t itS lOwer modes. Then describe the substrUcture's equations of motion through the lower modes,hence greatly reduce the number Of degree-of-freedom of the substrurcture. Finally,synthesize every substructure's equations of motion into the whole system's ones according to the inner boundary conditions. |
