摘　　要：为提高国产电脑袜机的设计与研发水平,运用现代机械设计分析软件ANSYS/LS-DYNA显性动力学分析模块对电脑袜机成圈机件进行动态仿真分析,主要研究电脑袜机编织过程中织针与三角接触碰撞时织针的响应情况,包括织针的位移、速度、加速度及受力情况。实验分析结果与理论分析对比表明,ANSYS/LS-DYNA分析方法能准确地模拟织针的运动情况及复杂的动态受力情况,为电脑袜机成圈系统的优化设计提供了一种可靠的理论分析方法。The present work was undertaken with a view to raising the level of design and development of domestic computer hosiery machine. The modem mechanical design software ANSYS/I.S-DYNA dynamics analysis module was used to perform dynamic stimulation and analysis of the knitting system of the computer hosiery machine, focusing on the response of the needle at the time when it comes into contact or impact with the cam （including displacement, velocity, acceleration and force bearing）. It has been proven by comparing the experimental results with those of theoretical analysis that the ANSYS/LS-DYNA analytical method can exactly simulate needle＇s movement and complicated dynamic force bearing situation, thus providing a reliable theoretical analytical method for optimizing the design of the knitting system of the computer hosiery machine.
