【摘要】 车轮是汽车的关键结构件,车轮的结构及性能直接影响着整车的安全性和可靠性。同时,车轮的轻量化也是整车轻量化的重要内容。本文针对某型钢制车轮,使用有限元工程软件进行了系统的应力计算及寿命评估,在此基础上,使用含铌高强钢进行了替代设计和疲劳寿命分析。研究结果表明,使用含铌高强钢进行轻量化设计,在满足国家标准的情况下,可以有效减轻车轮的质量,提高其市场竞争力。更多还原

【Abstract】 The wheel ispivotalstructural component in automobile.The safety and reliability of the car are influenced by the structure and properties of the wheel directly.In the meantime,the wheel of light is also an important part of the whole vehicle lightweight design.The simulation of a steel wheel’ s fatigue strength and life is carried out by using the finite element software.Then the alternative design and fatigue life analysis are done with the high strength steel which containing Nb.The results show thatlightweight design can reduce the quality of the wheel and enhance its market competitiveness effectively in the case of meet the national standard.更多还原
