摘　　要：国内电脑横机大都采用传统手法进行结构设计,机器运动稳定性不高,缺乏现代机械设计方法。针对这些问题,以WSG225C型全自动电脑横机为研究对象,对全自动电脑横机的成圈机构进行了研究,分析了织针在走针过程中与三角的作用力,计算关键编织工艺点,采用Solidworks软件建立了织针与三角三维实体模型,并应用Solidworks Motion进行运动仿真,得到走针运动位移、速度、加速度仿真曲线。运动仿真结果表明:当设定横机编织速度为1.20m/s时,织针走针的最高速度为1.86m/s、最大加速度为1.48m/s^2。由横机高速图像测试结果可知,测试数据与理论分析结果有较好的一致性。For computerized flat knitting machine in China, the structure design is conducted mostly with the traditional method. Thus, the motion stability of the machine is not high, and there is lack of modern machinery design method. For these problems, WSG225C fully automatic computerized flat knitting machine was chosen as the research object to study knitting element of fully automatic computerized flat knitting machine, analyze the acting force of knitting and triangle in the needling process and figure out key knitting technical points. SolidWorks software was applied to establish three dimensional model of knitting and triangle. Besides, motion simulation was conducted with Solidworks Motion to gain the displacement, velocity and acceleration simulation curves of needling motion. The results show that the knitting speed of the whole machine is 1.20 m/s, the maximum speed of knitting needles is 1.86 m/s and the maximum acceleration is 1.48 m/s^2. From the high speed image test results of the flat knitting machine, it is found that the test data is well consistent with the theoretical analysis results.
