AB - The adhesion coefficient of railway wheel, which is also called as friction coefficient between wheel and rail is an important factor for obtaining the sufficient tractive force and the reliable braking performance at high speed operation of train. The adhesion coefficient can be affected by the conditionsof the interface and the materials existing between the wheel and the rail such as oil, water and leaves. It could be also changed by a method to reduce the wear of the wheel and surface treatment of the wheel tread for higher adhesion coefficient. The friction coefficient is also well known as one of the factors which should be controlled carefully for securing the running safety of train. Therefore the investigation of the influence of the friction coefficient of wheel tread on the running safety of the vehicle was investigated. The results show that the effect of curve radius on the derailment coefficient is larger than that of the difference of the tread friction coefficient between left wheels and right wheels.

초록

The adhesion coefficient of railway wheel, which is also called as friction coefficient between wheel and rail is an important factor for obtaining the sufficient tractive force and the reliable braking performance at high speed operation of train. The adhesion coefficient can be affected by the conditionsof the interface and the materials existing between the wheel and the rail such as oil, water and leaves. It could be also changed by a method to reduce the wear of the wheel and surface treatment of the wheel tread for higher adhesion coefficient. The friction coefficient is also well known as one of the factors which should be controlled carefully for securing the running safety of train. Therefore the investigation of the influence of the friction coefficient of wheel tread on the running safety of the vehicle was investigated. The results show that the effect of curve radius on the derailment coefficient is larger than that of the difference of the tread friction coefficient between left wheels and right wheels.
