Simulation and Parameter Optimization of Flexible Wheel Hub Bearings Based on Romax
The inner and outer rings of hub bearings,as well as the small inner rings,are discretized into meshes in this study,and the mesh files are imported into Romax-Designer software to build the full flexible models for the inner and outer rings of hub bearings.The influence of axial load,radial load and overturning moment on bearings is analyzed,and the single factor simulation tests of bearing design parameters(including contact angle,number of rolling elements,ball diameter,column spacing and axial working clearance)are carried out respectively for bearing stress,life and minimum oil film thickness.The calculated data are processed by orthogonal test method to obtain the primary and secondary factors affecting bearing performance and the optimal combination.This method can provide necessary reference for engineers to design wheel hub bearings.
