基于温升模型计算长大下坡

Calculation of Long Steep Downhill Based on Temperature Rising Model

随着山区公路建设越来越多,长大下坡的安全问题也越来越严重,而目前规范中缺少针对长大下坡的规定和有效的计算模型。利用世界道路协会提供的《道路安全手册》中的计算模型对某公路的连续下坡路段制动片温度进行分析,模拟计算出不同类型车辆制动片的温度分布曲线,以供同行参考。

With the development of mountain highway construction, long steep downhill security issues be- come more and more serious, and the requirements and effective calculating model for long steep downhill are lacking in current specifications. In this paper, the calculating model from ＂Road Security Manual＂ by the World Road Association is adopted for application. Through the analysis of brake pads temperature on continuous down- hill section, temperature distribution curves for different types vehicles brake pads are simulated and calculated, which can provide reference for peer.
