深刻理解轮轨的粘着特性对实现铁道高速运行以及更快加速与减速具有重要意义。从弹性流体润滑理论的分析结果 ,介绍轮轨接触部分存在水膜时使粘着系数下降的机理
A deep understanding of the wheel-rail adhesion characteristics is of great significance for achieving high-speed railway operation and faster acceleration and deceleration. Based on the analysis results of the theory of elastic fluid lubrication, the mechanism of decreasing the adhesion coefficient in the presence of water film at the wheel-rail contact is introduced
