油介质条件下轮轨黏着特性的试验研究
Experimental Study on Wheel/Rail Adhesion Characteristics under Oil Medium Condition
摘要
Abstract
The effects of different wheel speed and axle load on wheel/rail adhesion coefficient were investigated under three polluted conditions of oil medium, namely, waste oil, the mixture of waste oil and water as well as the mixture of waste oil, water and sand using JD-1 wheel/rail simulation testers. The results indicate that when the train speed is 90 km · h-1, the wheel/rail creep characteristics under waste oil, the mixture of waste oil and water conditions have no obvious difference (Adhesion coefficient decreases when water is added). The difference of wheel/rail adhesion coefficient is smaller when the axle load is 21 and 23 t respectively under waste oil and the mixture of waste oil and water condition. The adhesion coefficient under 25 t axle load condition is obviously larger than that under the axle loads of 21 and 23 t However, the wheel/rail surface has no serious damage under different axle load conditions. The adhesion coefficient increases markedly under the mixture of waste oil, water and sand condition. However, wheel/rail surface damage is seriously worsened at the same time. Wheel/rail adhesion coefficient decreases with the increase of train speed when wheel/rail surface is polluted by waste oil and the mixture of waste oil and water.关键词
