| 摘 要： | 提出了一种新的自然坐标选择方法,将各种传统的自然坐标选择集合视为一种有机整体,称作自然坐标系.选择过程分为2步:首先为多刚体系统每个构件建立一个标准自然坐标系;然后在标准自然坐标系上施加基本调节操作得到实际的自然坐标系.新方法适用于各种传统构件类型,同时兼容各种传统方法,可作为统一的自然坐标选择方法.实例对比验证了新方法的有效性和兼容性.

| Abstract: | A new method was presented to select all the natural coordinates for a rigid multidbody system in a rational way.Based on a novel idea(natural-coordinate system),a so-called standard natural-coordinate system for every rigid element was built.Then,this system was adapted to the joints attached to the element,resulting in an actual natural-coordinate system,in which all the rational natural coordinates for the body were included.Without most of the conventional shortcomings enumerated here,the new method ser... |
