摘要: 针对国产双针筒电脑袜机机械设计的不完善,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6.7×107 m/s2,印证了双针筒电脑袜机高速运动的平稳性。

Abstract: According to the imperfect design level of domestic double-cylinder computer hosiery machine and lack of the theory research for the key mechanisms, it is mainly researched the dynamic analysis of the knitting element for double-cylinder computer hosiery machine. The SolidWorks software has wide functions which are 3D mechanism structural design, product modeling, and design optimization function. The SolidWorks was applied to set up the 3D 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 computer hosiery machine is in high-speed motion.
