高速工业缝纫机动力学仿真与分析

Dynamics Simulation and Analysis in High-speed Sewing Machine

分析了典型的高速工业缝纫机主要的运动构件及其运动原理,通过Pro/E和ADAMS建立的虚拟样机,对高速工业缝纫机中最关键的机构-刺布挑线机构进行运动学和动力学的分析,通过改进刺布机构连杆的长度,使该高速运动机构运动的更平稳。动力学分析的结果为机构、机架以及支承的设计和改进提供有效的依据。

Analysis of main moving structures of typic high-speed sewing machine and its working principle, the virtue machine was established by PRO/E and ADAMS. The most important mechanism the athletics and dynamics of the puncturing mechanism in the machine were analyzed. Through changing the length of linkage in puncturing machine, the high-speed machine can be working more smoothly. The results of the dynamics analysis offer effective basis for design and improvement of the mechanisms and the crust of the machine. [ Ch,7 fig. 9 ref. ]
