Model-building for slot needle′s six-bar linkage of high speed warp knitting machine based on UG

The purposes of this study were to analyze the mechanical properties of the slot needle′s six-bar linkage of high-speed warp knitting machine,reduce the impact of movement,and improve the stability during high-speed operation.The kineto-elastodynamic analysis(KED) method of multivariate flexible mechanism was applied to analyze the elastodynamics of the slot needle′s six-bar linkage.Model-building analysis of the slot needle′s six-bar linkage was carried out based on the technique of UG,and the flexible variation of the slot needle during high speed operation was systematically studied.The UG was applied to simulate the change of slot needle′s displacement,velocity,and acceleration under different operational conditions by using a computer;and the correctness of the KED analysis method of knitting elements was verified.This study provides a theoretical basis for structural design and optimization of the slot needle′s six-bar linkage.
