摘要
平面闭链机构及机械系统中广泛存在的过约束导致了机械性能的一系列有害影响 ,已经受到机械结构设计者的充分重视 ,提出了多种机构过约束的分析方法 ,但是这些方法还存在一些不足 ,还需进一步发展完善。笔者针对 2种常用的机构过约束分析方法公式计算法和回路自由度分析法存在的不足 ,在对其深入、系统研究的基础上 ,将 2种方法相结合 ,得到了一种较实用的、且便于计算机辅助分析的机构过约束分析方法 ,并提出了一些机构过约束分析的新的见解。
Overconstraints exist widely in planar closed chain mechanisms and mechanical systems result in a series of detrimental influences on behavior of machines, and attention is given to them by machine designer. Some analysis methods of overconstraints in planar closed chain mechanisms are presented, and more study due to the faultiness of these methods. In accordance with faultiness of two common kind of methods, formulas method and loop analysis method of degrees of freedom, and by combining these two methods, an useful mechanism overconstraints analysis method which is convenient for computer aided overconstraints analysis is gained via research on the two methods thoroughly and systematically, and some new views about mechanism overconstraints analysis are presented.
