摘要
轮毂是汽车运行时的主要承载部件,对于汽车安全行驶和可靠运行起着重要作用。特别对于设计者而言,其各方面的性能都应得到重视。文章以家用汽车轮胎的轮毂(18×7.5J)为研究对象,利用通用设计软件SolidWorks建立轮毂仿真模型,而后将轮毂仿真模型导入ANSYS19.2中的geometry模块中进行分析,并且参考国标,在材料库输入铝合金A356的相关参数,得到铝合金A356的S-N曲线,最后求解得到轮毂在周期性弯曲载荷下的安全系数和使用寿命分布云图,根据以上仿真结果,判断轮毂是否符合使用要求,对设计人员具有指导作用。
As an important part of the car wheel,the wheel hub has a significant impact on the safety and reliability of the car.Especially for designers,all aspects of its performance should be paid attention to.This paper takes the wheel hub(18×7.5J)of the family car tire as the research object,establishes the 3D model of the wheel hub through the 3D software SolidWorks,imports it into the simulation software for simulation analysis,and establishes the fatigue life curve(S-N curve)of aluminum alloy(A356),through the analysis to obtain the safety factor and fatigue life cloud diagram of the hub,according to the above simulation results,determine whether the hub meets the requirements of use,which has a guiding role for the designer.
