摘要
为确保轮毂在满足性能和使用要求的前提下,减轻轮毂质量,缩短产品研发周期,降低生产成本,文章论述了低压铸造铝合金车轮产品设计过程的重要环节——强度与疲劳实验有限元分析,利用UG软件,找出最大应力集中区域,采用轮辐厚度减小0.5mm、轮辋厚度从原来的5.2mm减小到4.8mm及轮辐靠近轮芯处过渡圆角的半径从30mm增加到60mm的方法,使应力分布均匀,重新进行强度校核,表明满足强度与寿命要求,提高了材料的利用率,达到了产品轻量化的目的。采用有限元方法能缩短设计周期、降低生产成本,为企业带来经济效益。
In order to reduce wheel hub weight, shorten the development cycle and cut production cost in the case of ensuring wheel hub performance keep stable, this paper introduces the essentials of low-pressure casting aluminum alloy wheel-FEA for analyzing strength and fatigue. Using UG to find the max stress zone, decrease wheel spoke 0.5mm, rim width is reduced from 5.2mm to 4.8mm, radius of rounded corner is increased from 30mm to 60mm, allowing stress well-distributed. Re-verifying strength shows that wheel hub meets the specification in its strength and lifetime, increasing aluminum alloy utilization ration, achieve to reduce weight. FEA can shorten design cycle, reduce production cost, bring economical effect for enterprises.
