摘要
以有限元分析方法为基础，采用动态子结构模态综合法（ＣＭＳ法）对弹性连杆机构进行了机构运动弹性动力分析（ＫＥＤ分析），探讨了自由度缩减技术在复杂时变机构系统分析中的应用．本文的工作为降低弹性连杆机构运动弹性动力分析的工作量，提高计算效率提供了一种方法，同时为机构的弹性动力综合与优化设计提供了有效分析手段．
Based upon the finite element method, dynamic substructure component mode synthesis is used to analyse elastic-linkage mechanism. The application of the reduction techniques of model in the large and complicated time-variably mechanism system is discussed.The results of this paper provide an efficient and feasible method for mechanism design optimization and can be used in practical mechanism design.
