空间连杆机构中四面体法关于单元类别的判定法则

Judgement on the Types of Units in Tetrahedron Solutions for Spatial Linkage Mechanisms

四面体法在解决实际问题时涉及到单元类别的判定问题。单元类别的判定有助于避免单元形成过程中矢量环方程处理的盲目性。本文就一般空间连杆机构中隐含单元的类别判定作了较深入的研究，给出了相应的判定法则。

The judgement of unit type is inevitably encounterred with in solving the problems of spatial mechanisms using Tetrahedron Solutions.By judging the types of units implicated in spatial mechanisms,the blindness in processing the vector loop equations is avoided.This paper does deep research on the method of judging the types of units in general spatial linkage mechanisms and puts forward corresponding criteria.
