摘要： 采用新一代钢铁材料超级钢代替原有的普通强度钢材制造中型客车或货车车轮,以此实现汽车减重、降低油耗和减少环境污染.并针对车轮动态弯曲疲劳试验建立了3种中型客车车轮的静态线性有限元模型,通过模拟计算确定车轮结构的危险点,反映应力集中程度.同时对采用超级钢制成的一组车轮进行动态弯曲疲劳试验.模拟和实验结果表明,采用超级钢生产的车轮在轮辐厚度减少2.5 mm,总质量减少10 kg的情况下仍能达到动态弯曲疲劳试验标准.

Abstract: To implement the weight reduction, low fuel consumption and pollution control, the new-generation ultra-fine grain steel has been used to make automotive wheel spoke instead of common high-strength steel. Static linear FEM models were thus developed to test dynamically different wheels' cornering fatigue for 3 medium-sized buses. The models can simulate and calculate the critical points in different wheel constructions and reflect the stress concentration on these points. Testing results revealed that the thickness of those wheel spoke which are made from the ultra-fine grain steel can be decreased by 2.5 mm with total weight decreased by 10 kg, and all the wheel spokes are up to standard.
