Dynamics analysis of computer hosiery machine′s knitting system based on ANSYS/LS-DYNA

The present work was undertaken with a view to raising the level of design and development of domestic computer hosiery machine.The modern mechanical design software ANSYS/LS-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.
