Simulation of sewing machine mechanisms using program package ADAMS Available to Purchase

Use of programme package ADAMS to simulate the sewing machine mechanisms is presented within this contribution. The simulation of needle bar mechanism was carried out. The influence of velocity changes of the main shaft on velocities and acceleration of sewing needle in the penetration area is described on the basis of simulation results. Achieved data could be used for calculation of needle penetration force. The influence of length modification of needle bar mechanism elements on sewing needle velocity and acceleration is also presented. This analysis could contribute to better understanding of sewing machine activity.
