Abstract
In this paper, the dynamic characteristics of lunge material mechanism in household sewing machine are simulated with the MATLAB software and the dynamics simulation software ADAMS. The displacement, velocity, acceleration of lunge needle is calculated with MATLAB and simulated with ADAMS. Then the curves of displacement, velocity, acceleration of lunge needle VS time are plotted with the two different softwares respectively. The angular acceleration and drive torque of crank is calculated and simulated either. Then, the contrast and discussion about the calculation and simulation is carried on. This research has some reference value for design and simulation of lunge material mechanism in sewing machine and other machines.
