摘要
在提出弯扭线的基础上,用曲面回扫方法结合刚体有限转动的有关理论研究超细长弹性杆的空间结构及空间曲面图形的描绘,为分析弹性杆的自身接触问题和动力学性态的计算机数值仿真及其图形后处理提供了模型和算法的支持.
Using Swept Volumes method, combining with limited rotation theory of rigid body, this paper stud- ies the elastic rod＇ s spatial structure, including the elastic rod＇ s spatial shape, depicts the surface figure of the rod, provides model and algorithm supprots for numerical simulation and post-processing of the numerical results, as well as studies the dynamical properties of the elastic rod.
