摘要
为了满足轿车高速、大功率和刹车平稳可靠的需要,轮胎扁平化成为轿车工业设计和发展的趋势.该文重点研究轮胎扁平化后钢圈轮辋的强度问题,建立了钢圈轮辋的有限元计算模型,计算了现用材料不同厚度钢圈轮辋的强度和钢圈轮辋上不同位置处的最大承载力以及采用新材料时钢圈轮辋的最大承载力,并进行了冷轧工艺对强度影响的试验,得出了一些对提高钢圈强度有意义的结论.
To meet the requirements of high-speed, high power and braking reliability, tyre flattening has become a tendency in the automobile industry. This paper stresses the strength of steel ring after tyre flattening. A calculation model of the steel ring is established using FEM. The strength of tyre rims made of current materials with different thickness and maximum loads on different parts of tyre rim are calculated. The maximum load of tyre rim made of new materials is also calculated. Influence of cold rolling technique on the strength of tyre rims is tested. According to these calculations, useful conclusions for increasing strength of the rims can be obtained.
