Finite Element Analysis of a passenger car aluminum alloy wheel hub based on OptiStruct
摘要
Abstract
To evaluate the structural performance of a passenger car aluminum alloy wheel hub and explore its lightweight potential,finite element models of the wheel hub under a bending condition and 36 sets of radial multi-angle loading conditions were established based on OptiStruct.A local peak stress of 293 MPa was observed on the flange surface under the bending condition.By introducing the hot spot stress method,the structural hot spot stress was obtained as 131.4 MPa by taking the average stress of five adjacent elements,thereby avoiding misjudgment caused by direct comparison with the yield strength.The 36 sets of radial loading conditions indicated that the maximum equivalent stress of the wheel hub fluctuated periodically with the loading angle(ranging from 113 MPa～146 MPa),demonstrating the limitation of single-angle loading.Since the principal stress in the wheel hub body was only 20 MPa～70 MPa,lightweight schemes such as increasing the transition fillet,employing variable-thickness spokes,and optimizing weight-reducing pockets were proposed.The research findings provide a reference for the refined design of aluminum alloy wheel hubs.关键词
