Abstract:

The design methods of domestic dual input computerized hosiery machine was conventional. It was not only lack of appropriate analysis and simulation research for institutional dynamics, but also its stability needed to be improved. The instantaneous force status of needle and cams was analyzed based on the dual input computerized hosiery machine’s knitting theory and key process points. 3-D model of knitting element was created with SolidWorks 3-D modeling technology, and then the research of mechanics dynamics was conducted. ANSYS finite-element analysis technology was employed to simulate the movement of main knitting element. The curve of needle’s displacement, velocity and acceleration were acquired by the above analyses. According to the simulation parameters of needle’s movement, the knitting element was optimized. The results reveal that acceleration reach a maximum of 0.75 ×10 ²m/s ² when knitting time is 0.19 s. In comparison with the value before design optimization of knitting element, it reduces significantly, and the smoothness of  dual input computerized hosiery machine improves.
