Analysis and optimisation of the needle driver mechanism with clearance in the sewing device
摘要
Abstract
The sewing device was designed and optimized with the objective of improving the rate of successful sewing in carbon fiber composite materials.This paper investigates the dynamic characteristics of the joint clearance of the needle driver mechanism in a sewing device.The joint and dynamic model of the needle driver mechanism have been developed,and the contact force models for the three clearance-containing rotary joint have been evalua-ted.A dynamic simulation of the clearance model is conducted using MATLAB software to examine the influence of three contact force models on the dynamic performance of the needle driver mechanism.Subsequently,a physical sewing device is constructed for the purpose of conducting an experimental analysis.The results of the study show that,the hydrodynamic contact force model is selected for analysis of the clearance-containing rotary joint.This ap-proach results in a closer alignment between the dynamic characteristics of the mechanism and that of the ideal rota-ry joint,which in turn reduces the vibration of the needle driver mechanism,thereby increasing the rate of success-ful sewing in carbon fiber composite materials and optimizing the sewing stitches.Thus,it is demonstrated that the contact force model as well as the mechanism design meets the requirements of stitched carbon fiber composite mate-rials.关键词
