摘　　要：为了探讨高寒地区恶劣条件下轮轨接触状态特性,确保列车运行安全,研究了运营速度400 km/h的高速列车在俄罗斯高寒地区轮轨接触的粘着特性,首先建立了相应的整车动力学模型及轮轨滚动接触模型,然后在此基础上,研究了高寒地区轮轨接触粘着系数的主要影响因素,求解出相关的峰值粘着曲线和粘着曲面,最后在保证轮轨良好粘着状态的前提下,充分利用粘着条件设计了列车制动减速度曲线,并验证了该曲线的正确性、合理性、有效性。In order to grasp the wheel/rail contact state in frigid area harsh conditions and ensure the safe of the train＇s operation,this paper studied the wheel/rail contact adhesion properties of the high-speed train which could reach 400 km/h in frigid area,in Russia.The related vehicle dynamics model and the wheel/rail rolling contact model were established.On the basis of above,the main influence factor of wheel/rail contact adhesive coefficient in frigid area was researched,and the correlative peak of adhesion curve and adhesion surface was obtained.Combined with project,under the premise of good wheel/rail contact state and with full use of adhesion conditions,the braking deceleration curve of the train was designed and verified with the correctness,rationality and validity.
