Abstract:

Based on research on the knitting processes, an impact mechanic model for knitting elements was established to investigate the variation of the impact force in vertical direction between the cam and the select jack. The variation of the displacement, velocity, acceleration of the select jack and the stability for the needles’ moving has been confirmed by the simulation of knitting process based on the software ANSYS/LS-DYNA. Furthermore, the variation of the select jack has been confirmed by experimental measurement during the knitting process. The data of the experiment results were in accordance with the ANSYS’ simulation which verified the correctness of the ANSYS’ analysis. It provided a theoretic basis for the design of computerized flat knitting machines.
