摘要
系统分析了道岔区轨道横向刚度薄弱地段和横向刚度加强后列车轮轨动力作用的影响规律,提出并设计了适用于道岔导曲部位的减振型轨撑扣件的加强方案,并通过现场试验,实现了良好的轨道强化效果。
This paper analyzed the influence rules of train wheel/rail dynamic interaction in turnout zone rail transverse stiffness weak section and after transverse stiffness strengthening,put forward and designed the strengthening program suitable for vibration type switch support fastener in turnout guide rail bending part,and through the field test,achieve good track strengthening effect.
