摘要： 利用传统的模态综合法进行多柔体系统动力学建模时，没有考虑到控制系统设计技术的承受能力和激励的特点,保留的大量低频子结构模态对于整体控制目标没有贡献，反而加大了组合的整体方程的复杂程度．因此，为考虑部件级的降阶，可以在传统的部件组合之前，对部件模态坐标独立变换处理，去掉系统中弱能控和弱能观部分，而剩下的模态仍可使后继分析有必要的精度，从而建立降阶的动力学方程．

Abstract: The disadvantage of the CM S methods is that they ignore the bearing capacity of control system ’S design technology and the features of stimulation．The preservation of a large number of low-frequency appendage modes contributes nothing to the objective of the entire control system ，and conversely increases the complexity of the multi-body model．Hence，to achieve the component model reduction，it is feasible to conduct coordinate transformation on component modes and eliminate the least controllable and least-observable parts to conserve the necessary precision of the remaining modes for subsequent analysis，and finally build the reduction dynamic model before traditional components combination．
Key words: multi-flexible system    component mode synthesis(CMS) methods    the two-stage component model reduction
