汽车车轮

• At present , aluminium and its alloy are widely used in wheels . the motive of this paper is to reduce ulteriorly the weight of wheel in virtue of advanced design method
  目前，大部分汽车车轮已使用铝及其合金做作为材料，利用现代设计方法，在此基础上进一步实现车轮的轻量化则是本文的研究所在。
• In conclusion , some inherent rules are mainly studied in this paper , the effects of the vehicle speed and the roadway surface condition on the random dynamic loads of the wheels are analyzed
  综上所述,本文主要研究了汽车车轮动载荷的内在规律性,分析了路面不平度和车速等因素对汽车车轮动载荷的影响。
