| 摘 要： | 机构的第2类可动性。是机构分析与综合所要探讨的基本问题之一。本文对一般形式的空间RRRSR五杆机构的可动性进行分析。通过拆开运动副,分析运动轨迹,根据其雅可比矩阵奇异获得各位形分支的边界后,采用拓朴变换原理,讨论得出该机构的装配条件和连架杆的运动情况。为空间多杆机构的第2类可动性分析,提供了一条方便、实用的途径。

| Abstract: | The second movability of mechanisms is one of the basic problems on mechanism analyses and syntheses. This paper discusses the movability of general spatial five-bar (RRRSR) mechanisms by taking apart a joint, analysing the moving paths and obtaining the boundaries of all different configuration branches.The assembly conditions and the movement ranges of links jointed on the frame are derived. Topologie transformation is used. Several numeral examples are given. |

| Keywords: | spatial linkage movability branch of configuration Jacobian matrix topologic transformation |
