基于能量等价损耗原理的路面抗滑性能预测

Prediction of Skid Resistance Based on Energy-damage Equivalency Criterion

目前对路面抗滑性能预测多采用经验回归的方式,摩擦力学与路面磨耗之间的力学关系尚未明确,导致路面抗滑性能预测模型的推广应用存在一定的局限性.文中基于能量等价损耗的概念,通过单一轮胎对路面损伤程度的实测,运用能量等价损耗原理可以推算出不同类型的车辆对路面的损耗程度的量化指标.

The pridiction of skid resistance has a important practical significance. However, as most of the methods for skid resistance prediction using empirical models,which lead to the limitation for the application of this models, and the relationship between friction mechanics and mechanical wear of pavement is still indeterminate. In this paper an energy-based damage equivalency criterion is proposed. Through evaluating a criterion by which damage induced by one vehicle type can be compared with that caused by another one. In order to evaluate the polishing action exerted by different types of vehicle.
