摘　　要：本文研究了车轮踏面损伤对轨道的冲击压力与列车运行速度、轮载及踏面损伤程度的规律，提出了衡量车轮踏面损伤程度的新概念——踏面损伤当量。使轨道冲击压力实量数据与车轮踏面损伤程度有了量化关系，并建议把损伤程度分为四级。This paper describes the relationship between the damage degree of wheel tread and the impact load on track caused by the damage,the operating sppeed of train and the wheel load.A new concept tread damage equivalent is presented for evaluating the damage degree.Thereby the relationship between the impact load on track and the tread damage degree is quantified.In addifion,it is suggested that the fread damage degree as an important parameter of railway scientific management be divided into four grades.
