中文摘要：

利用JD-1轮轨模拟试验机研究水和油介质工况下磁场对轮轨黏着特性的影响。结果表明：在水和油介质工况下，磁场作用下的轮轨黏着力大于无磁场作用的黏着力，其中加磁水介质黏着力相对增幅达20％，加磁油介质黏着力相对增幅达50％；水和油介质工况下，施加磁场时速度对轮轨黏着力影响不大。

英文摘要：

The effect of magnetic field on adhesion characteristic of wheel/rail was investigated under water and oil con-ditions using JD-1 wheel/rail simulation facilities. The results indicate that the magnetic field can increase obviously adhesion force of wheel/rail under water and oil conditions. The increase rate of adhesion force under water condition exceeds 20% and the increase rate of adhesion force under oil condition is 50%. Under water and oil conditions,the speed has no obvious effect on adhesion force of wheel/rail when magnetic field is used.
