Knitting Motion Analysis and Mechanism Design for Multi-bar Warp Knitting Machine
摘要
Abstract
On the basis of understanding basic principles for mechanism design of foreign warp knitting machines,knitting motion and the mechanism for performing the motion were studied sys-tematically.Firstly,knitting mechanism,knitting processes and its working principles were introduced and Stephenson 6-link transmission mechanism with intermittent function was designed.By sharing a three-thrown crank shaft,three 6-link transmission mechanisms and 3-DOF plane 8-link knitting sub-mechanism were concatenated.A 3-DOF plane 22-link knitting main mechanism with single driving axis was designed and its kinematics property was also analyzed.Secondly,the key feature points of knitting action were planned based on the configuration of guide needles and knitting processes and the polynomial function of each trajectory was obtained by least square method.Further,the whole physi-cal model of the 3-DOF plane 22-link knitting main mechanism was analyzed and optimum design of mechanism parameters was conducted based on the knitting action trajectory approaching using genet-ic algorithm.关键词
