摘要
基于Ｊｏｕｒｄａｉｎ变分原理建立了单变形体动力学程式化方程．提出了变形体浮动坐标系建立的一般原则，用集中质量有限单元法与正则模态分析法描述物体的弹性变形．得到的结果同单刚体动力学方程及结构体动力学方程兼容．
A set of computer-oriented dynamic equation of motion for a deformable body is derived by using Jourdain principle, the lumped mass finite element method and the normal modal analysis method. A new method for building float frame attached to deformable body is presented. The results obtained in this paper are compatible with those of dynamics of rigid body and structural dynamics. Two numerical examples are given finally.
