The Effect of the Shape and Parameters of the Knitting Needle on Cam-to-needle Impact Forces

摘要

Cam-to-needle impact forces and the shape of the impact pulse in weft-knitting are analyzed in detail by a mechanical model of viscously damped free vibration with one degree of freedom. The induced equations predict that the peak impact force, P_vm, and pulse frequency, f_p, are Directly proportional to the product of the natural circular frequency, ω, and the mass, m, of The needle.
