摘要
为研究轮毂应力大小及变形情况,针对安徽车桥自主研发的AQ5020127244410型轮毂进行建模,对静载和紧急制动两种工况分别添加载荷以及约束条件,分析轮毂受力及变形。结果表明,静止状态下,轮毂承受最大应力为101.73MPa,产生最大变形0.023mm。紧急制动状态下,轮毂承受最大应力122.07MPa,产生最大变形0.028625mm。紧急制动状态下,轮毂承受应力变形更大,轮毂承受应力小于材料许用应力,满足使用要求。
In order to study the stress and deformation of the hub,this paper designs the AQ5020127244410 wheel hub independently developed by Anhui Automobile Bridge,discusses the working conditions,adds loads and constraints to the static and emergency braking conditions,and analyzes the wheel hub.Force and deformation.The results show that the maximum stress of the wheel hub is 101.73 MPa at rest,resulting in a maximum deformation of 0.023 mm.In the emergency braking state,the hub is subjected to a maximum stress of 122.07 MPa,resulting in a maximum deformation of 0.028625 mm.In the emergency braking state,the hub is subjected to greater stress deformation,and the bearing stress of the wheel hub is less than the allowable stress of the material to meet the requirements for use.
