针对套圈整体抛磨中器壁构型及浮动支撑对抛磨效果影响尚不清晰的问题，通过EDEM与ADAMS耦合仿真试验，探究不同器壁构型和浮动支撑结构下颗粒介质动能和套圈各表面法向接触力分布规律。仿真结果表明，器壁构型与浮动支撑对颗粒介质流场影响显著，当容器截面形状为正六边形，内接圆直径为300 mm，支撑杆直径为15 mm，均布圆直径为70 mm时，套圈各表面法向接触力处于较高水平，且法向接触力分布相对均匀，适合抛磨。选取经仿真优化的相关参数搭建套圈整体抛磨试验平台，进行套圈整体抛磨试验。试验结果表明，抛磨后的套圈各表面粗糙度值明显下降，实现该工艺装备参数的基本优化。
Optimization of the vessel wall configuration and floating support of the overall finishing of bearing ring
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 in-vestigated 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 finish-ing tests were carried out.The experiment results indicate that the surface roughness values of the bearing ring decrease signifi-cantly after finishing,and the basic optimization of the equipment parameters of the process is achieved.
