Abstract

Abstract: To address the unclear influence of vessel wall configuration and floating support on the overall finishing of bearing ring,the kinetic energy of particle media and the normal contact force distribution law of each surface of the bearing ring were investigated by EDEM and ADAMS co-simulation tests under different vessel wall configurations and floating support structures. The simulation results show that the vessel wall configuration and floating support have significant influence on the particle media flow. When a vessel with the regular hexagonal cross-section,the inner circle diameter of 300 mm,the support bar diameter of 15 mm,and a uniformly distributed circle diameter of 70 mm is used,the normal contact force on each surface of the bearing ring is at a higher level and the distribution of normal contact force is relatively uniform,which is suitable for finishing. The relevant parameters optimized by simulation were selected to build the overall finishing of bearing ring test platform,and the overall finishing tests were carried out.The experiment results indicate that the surface roughness values of the bearing ring decrease significantly after finishing,and the basic optimization of the equipment parameters of the process is achieved.

Key words: overall finishing of bearing ring, vessel wall configuration, floating support, the kinetic energy of particle media, normal contact force distribution
