- Abstract:
- To clarify the applicability and application status of a brake drum temperature rise model for heavy vehicles and to provide the basis for the safety of vehicle on long and steep downgrades of highway，related literatures had been summarized. The temperature rise mechanism of the brake drum of large vehicles were reviewed. According to the modeling method, the brake drum temperature rise models were divided into the theoretical analysis models, software simulation models, and measured regression models, and the research status of the model was analyzed. The characteristics of each modeling method, the dominant modeling model and the auxiliary braking measures were commented respectively. Three long longitudinal slopes of mountainous highway in Yaan to Xichang section of Jingkun Highway （Beijing to Kunming） were selected as test sections, and the measured data were obtained of a downhill truck test. The temperature rise curves of typical mode and measured data were plotted, and the correlation and error were compared by SPSS, thus the applicability of each model was analyzed. The results show that the theoretical analysis model can better reflect the temperature rise in heavy vehicle under actual driving conditions, and the brake drum temperature rise model still can be further studied and developed. In the future, we should take the semihanging truck as the leading vehicle, with consider the influence of road curve, horizontal and longitudinal alignment combination, characteristics of driver braking behavior and climate environment on the temperature rise of brake drum. The braking characteristics of driver on downhill and temperature rise mechanism in combination with various auxiliary braking methods should also be studied, and then building the brake drum temperature rise model under the coupling effect of humanvehicleroadenvironment. Finally, the brake drum temperature rise model can be deeply applied to the control and optimization of longitudinal slope design, the traffic management and the safety risk rating on downhill. These can alleviate the coordination contradiction between the road and vehicle in China, and improve the traffic safety levels. 4 tabs, 3 figs, 56 refs.
