发布时间：2019-07-10 15:08
【摘要】：采用摩擦接触理论和有限元方法分别计算了路面不同结冰工况下的汽车制动距离,并进行现场制动试验验证。结果分析表明,采取防冰措施可大幅降低制动距离和提高行车安全性,建议冰雪天气控制行车速度不超过60km/h,小汽车和货车的车辆间距分别不低于80m和100m,且宜采取间断放行方式以策安全。

[Abstract]:The braking distance of automobile under different freezing conditions is calculated by friction contact theory and finite element method, and the field braking test is carried out to verify the braking distance. The results show that the braking distance can be greatly reduced and the driving safety can be improved by taking anti-ice measures. It is suggested that the driving speed should not exceed 60 km / h in ice and snow weather, and the vehicle spacing between cars and freight cars should not be less than 80 m and 100 m, respectively, and intermittent release should be adopted to make it safe.
