A physico-mechanical approach to analyzing nonlinear elasticity in sewing machine conical springs

Abstract

This study presents an innovative approach to addressing vibration issues in sewing machines used in the light industry. The research focuses on the experimental analysis of a novel conical spring mechanism designed to enhance shock absorption in the kick mechanism of sewing machines, employing a physico-mechanical approach. This methodology integrates principles from physics and mechanics to provide a nuanced understanding of the spring's nonlinear elasticity and its impact on vibration damping. The study outlines the experimental determination of the oscillation characteristics of the proposed mechanism, offering insights into its effective reaction properties. Comprehensive results of compressive strength and spring elasticity calculations are presented, along with an analysis of dynamic forces using the electrostrain method. This research contributes to the advancement of sewing machine technology by addressing critical vibration issues, potentially leading to improved product quality and increased operational efficiency in the light industry sector. The physico-mechanical approach adopted provides a rigorous foundation for future improvements in sewing machine design and operation.
