连杆机构分析的拓扑图论方法及应用软件

The topological method for linkages analysis and its applied software

经对平面连杆机构的五类基本杆件和运动副约束性质的分析,本文导出了用拓扑图论中的点边关联矩阵表达的拓扑变换,用这种拓扑变换可对任意连杆机构进行运动轨迹、速度、加速度和力分析。已研制出平面机构分析的通用源程序,可在计算机屏幕动态显示机构运动规律。已表明该方法及应用软件有许多优点。

By analyzing the five kinds of linkage and the restraints of kinematic pairs this paper has inferred the topological transformation which is expressed by the vertex-edge incidence matrix of topological graph. The moving track, velocity, acceleration and force analysis for arbitrary multi-bar linkage can be done by the topological transformation. The common souce program for arbitrary plan linkage analysis has been developed and can display the regularity of moving mechanisms on the screen of a computer. It has been shown that the developed method and its applied software have many advantages.
