车辆轮胎损耗模型

Vehicle Tyre Wear Prediction Model

本文以世界银行 HDM-Ⅲ模型中的轮胎损耗预估模型为基础,通过对上海和北京等地12个运输车队轮胎损耗的调查,运用所得数据对该模型进行了标定,建立了适合我国情况的胎面磨损率和翻新次数以及轮胎损耗量估算关系式。并结合燃油消耗模型中的车辆分类和行驶速度预估模型,建立了轮耗同路况的关系式。所建模型可同油耗模型等一起,成为车辆运营费用模型的组成部分。

Abstract In this paper,the Chinese tyre wear model is constructed by calibra- ting the corresponding model in the HDM-Ⅲ model of the World Bank.During the calibrating,a small scale user survey was made of 12 vehicle fleets,and then the rate of tread wear,the number of tyre retreads and the tyre wear of each fleet are calculated based on these survey data.According to the vehicle classification and the speed prediction model adopted in the fuel consumption prediction model,the rela- tionship between tyre wear and road condition is eventually established for 7 types of vehicles.
