Analysis of Rod Length Change in the Rapier Weft Insertion Mechanism Transmitted by Spatial Four Bars

Abstract:

In order to analysis kinematics characteristic of space four bar linkage weft insertion mechanism and the influence on movement law by connecting rod length change, mathematical models of every parts of the mechanism were proposed by the method of analysis, and through MATLAB programming, motion curves were obtained. The length range of connecting rod and rocker, and the impact of changes in length were also studied, and some corresponding conclusions were drawn. The motion characteristic curve of it has been in accord with the weft inserting requirements. The study of kinematics, especially the discussion of connecting rod length changes will pave the way for the further study of dynamics.
