Dynamic Optimization for Puncturing and Stirring Mechanisms of Sewing Machines
摘要
Abstract
Sewing machine is one of the most popular equipment in sewing industry. The puncturing and stirring mecha-nism is found to have a large influence on vibration and shock of the entire sewing machine. In this paper, a virtual prototype model of the puncturing and stirring mechanism of sewing machines was established for dynamic analysis. Based on the par-tial equilibrium theory, and taking minimizing the maximum inertia force of the needle-bar crank as the optimal objective, the mathematical model of optimization was established. By adjusting the parameters such as the mass and the location of the mass center of the mechanism, the best balance of the inertia force of the mechanism was achieved. The experimental re-sults indicate that the optimization method has some credibility, and the partial equilibrium method applied here is effective for analyzing vibration and noise problem of complex mechanical systems such as the high-speed industrial sewing ma-chines.关键词
