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.

This paper deals with the modification of the mechanical system of the needle bar. The purpose of this work is to reduce the vibration and noise of the sewing machine for creating a decorative stitch. A special floating needle is used to sew this stitch, in which two mechanical systems of needle bars handover through the sewn material, so that a perfect imitation of a hand stitch is created. The original system, which controls the release of the needle at the handover location by abruptly stopping the needle bar control element, could be replaced by a new system that uses magnetic force to release the needle. In addition to the usual design procedure, numerical simulations of the attractive force of the electromagnet are also used in the design of a suitable electromagnet. At the same time, an electrical circuit is also designed to allow the needle to be released and gripped quickly. The advantages of the new system lie not only in reducing vibrations and the associated increase in the operation speed of the machine, but also in making it easier for the machine to switch to possible automated or semi-automated production.
