| 摘 要： | 结构系统的动态分析大致有二类方法:多刚体动力学、有限元法,前者分析多刚体系统,后者分析弹性系统。对多刚体与弹性体组合系统的动态分析尚有许多待解决的问题。本文改进了有限元法,使之不仅能分析弹性系统,又能分析多刚体系统以及二者的组合系统。

| Abstract: | Dynamic analysis methods For structures arc generally divided into two kinds: multi rigid-body dynamics, finite element method. The former is used to analyse multi-rigid-body system, the latter is used to analyse elastic system. In dynamic analysis of the combined system of multi rigid-body and elastic body, many problems awaiting solution In this paper the improved finite element method is presented and applied to the analysis of not only clastic system, but also multi-rigid body system, and their combined system. |
