Dynamic characteristics analysis of conjugate cam beating-up mechanism of rapier loom

Abstract

It is of great significance to study the dynamics of conjugate cam beating-up mechanism, which can improve the kinematic accuracy and dynamic performance of the beating-up mechanism of the rapier loom, reduce the vibration of the loom and prolong the service life of the loom. Firstly, the dynamic model of conjugate cam beating-up mechanism is established based on Lagrange equation, and MATLAB and ADAMS software are used to calculate and simulate to verify the reliability and accuracy of the dynamic model. Secondly, the influence of cam spindle speed, component material properties and reed foot centroid position on the dynamic characteristics of the mechanism is studied, and the influence law of beating-up resistance on the driving torque is studied. Finally, through systematic analysis and research, it is concluded that the dynamic characteristics of beating-up mechanism of rapier loom should be improved by reasonably controlling the spindle speed, selecting component materials reasonably, optimizing the position of reed foot centroid, and reasonably selecting matching fabrics, so as to improve loom efficiency and fabric quality.
