摘　　要：在纺织机械机构的设计过程中,为能直接看到机构的动态运动过程及其任一点或杆的运动参数(位移、速度、加速度),依据平面连杆机构的基本组成原理和拓扑学知识,建立机构的结点基本信息数据库和约束关系数据库,分离出独立的基本杆组并对其求解,应用MatLab语言编制通用程序,建立了平面连杆机构的计算机辅助分析与仿真系统,并以经编机沉降片为例对结果进行验证。结果表明,对任一给定的机构,仅需输入已知信息,就可以得到其动态仿真图形及其任一点或杆的运动参数。During the process of designing textile mechanism, it would be helpful for the designer to view the whole dynamic kinetic course of the designed mechanism and the kinetic information （displacement, velocity, acceleration） of any point or linkages of the mechanism in the meantime. Based on the basic structure theory of planar linkage mechanism and topology, the node basic information database and restricting relation database of mechanism were established. The independent basic linkage groups were isolated and solved. The current program was compiled using MatLab and the computer aided analysis and simulation system of the planar linkage mechanism were developed. Warp knitting machine sinker was taken for example to validate the result. For any given mechanism, as long as the known information database of it was input, its dynamic simulation graph and kinetic information of any point or link can be gotten.
