摘　　要：针对国产双针筒电脑袜机机械设计不完善,缺乏对关键机构的理论分析,着重对双针筒电脑袜机成圈机件进行动力学分析。利用SolidWorks功能强大的三维机械结构设计,产品造型和设计优化功能,创建了成圈机件的三维模型。在此基础上将成圈机件实体模型导入ANSYS/LS-DYNA系统,实现了导针片、织针与三角的计算机运动仿真,研究了成圈机件接触碰撞时运动位移、速度、加速度及受力情况,进行了织针与三角的设计优化。并通过高速摄影和图像的数据处理,验证ANSYS/LS-DYNA研究结果的正确性。研究结果表明,织针最大加速度为6.7×107m/s2,印证了双针筒电脑袜机高速运动的平稳性。According to the imperfect design level of domestic double-cylinder computerized hosiery machine and lack of the theory research for the key mechanisms,it mainly researched the dynamic analysis of the knitting element for double-cylinder computerized hosiery machine.The SolidWorks software has wide functions which are 3-D mechanism structural design,product modeling,and design optimization function.The SolidWorks was applied to set up the 3-D model of knitting element.On this basis,the knitting element′s solid model was guided to ANSYS/LS-DYNA system which realized the computer′s movement simulation of the lead wire,the needle,and the cams.It also studied their displacement,velocity,acceleration,and force conditions when the contact-compact of the knitting elements happened.Then,the needle and the cam were optimized by design.Furthermore,the high-speed shooting and image data processing were applied to the experiment,and the research findings′ accuracy of the ANSYS/LS-DYNA was certified.The research findings show that the acceleration′s maximum value of the needle is 6.7×10^7 m/s^2,and the stability of the needle can be controlled when the double-cylinder computerized hosiery machine is in high-speed motion.
