摘　　要：本文从防冻液浓度对轮轨黏着系数的影响、天气条件对防冻液浓度的影响两个方面进行了模拟试验分析。通过试验分析,确认防冻液在自然天气条件下会发生浓度的变化,且随着防冻液浓度的增加,黏着系数呈现明显的下降趋势,二者成反比关系,黏着系数的变化进而影响轨道车辆的制动距离。This paper do some simulation test and analysis from the impact of both antifreeze concentration on wheel-rail adhesion coefficient and weather conditions on the antifreeze concentration.Through experimental analysis,confirmed that antifreeze concentration changes under some natural weather conditions,and with the increasing concentration of antifreeze,adhesion coefficient showing a clear downward trend,inversely proportional relationship between the two.
