【摘要】:采用摩擦接觸理論和有限元方法分別計算了路面不同結(jié)冰工況下的汽車制動距離,并進行現(xiàn)場制動試驗驗證。結(jié)果分析表明,采取防冰措施可大幅降低制動距離和提高行車安全性,建議冰雪天氣控制行車速度不超過60km/h,小汽車和貨車的車輛間距分別不低于80m和100m,且宜采取間斷放行方式以策安全。

[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.
