Mechatronic design optimization of the mechanism in a sewing machine

Abstract

This work deals with the multiobjective mechatronic design optimization of a sewing machine. The mechatronic model of the machine is developed based on the coupling of the needle bar and thread take-up lever mechanism dynamic and the DC motor models. Based on the mechatronic model, the consumed energy, the DC motor load, and the coupler tracking error are minimized, simultaneously. The multiobjective imperialist competitive algorithm is used to perform the mechatronic design optimization. The obtained results show that if the user allows a small tracking error, he can significantly reduce the motor load, the vibration, and the consumed energy of the sewing machine.

Defect free optimization of a polycentric prosthetic knee design using imperialist competition-inspired optimization method

“…Differential evolution (DE) and simulated annealing (SA) have been used in the design optimization of four bar linkage with and without clearances (CHEN and ZHU 2009, Lin 2010, Naresh 2019. The imperialist competitive algorithm (ICA) has been also used to find the optimal design planar mechanisms (Bilel et al 2018). Several researchers focused on studying the drawbacks of the above algorithms and developed other improved versions.…”
