Abstract:

The vibration of the rapier loom conjugate cam beating-up mechanism results in the sley angular acceleration deviation, reduces the weaving quality, and shortens the conjugate cam. To solve these problems, conjugate cams beating-up mechanism is reasonably simplified. Flexible follower is discretized by Rayleigh-Ritz method and the dynamic equation of flexible follower is established based on the Lagrange equations. The dynamic simulation for the beating-up mechanism with flexible follower conjugate cams is carried out by Matlab. In the process of simulation, the method of reducing the  vibration of beating up mechanism is explored by changing the structure parameters of the beating-up machanism.The simulation results show that the angular acceleration of the sley will fluctuate significantly due to the transverse vibration. A method for reducing the angular acceleration deflection and reducing vibration of mechanism is proposed by reducing the mass of the sley feet.
