In order to improve the lateral stability of the train,the horizontal adhesion characteristics of the wheel and rail were studied.The experiments on the lateral adhesion characteristics of wheel and rail were carried out under different media conditions by using the transverse wheelrail rolling vibration test bench,and the effects of various axle load and speed on the lateral adhesion characteristics of wheel and rail were analyzed.The results show that the lateral adhesion coefficient of the wheel and rail is reduced under the conditions of water and oil medium compared with dry state condition.The lateral adhesion coefficient is increased with the increase of axial load under different media conditions.The lateral adhesion coefficient is decreased with the increase of the speed under the dry state and water medium,while it is increased with the increase of the speed under the oil medium,but the change range is not very large.The lateral adhesion coefficient is increased when sanding on the wheelrail contact surface,but it has a certain impact on wheel and rail damage.
