摘要
道岔与一般正线的区别就在于它多变的轮轨接触几何关系、复杂的轨线布置以及走行线路的转换。以一般线路轮对踏面与钢轨轨头接触关系为基础 ,考虑转辙器区尖轨与基本轨之间、翼轨与心轨、主轨与护轨以及心轨之间的空间结构和平面布置 ,本文模拟计算了转辙器区和辙叉区轮对与相应轨线的接触与冲击情况 ,得到了较为准确的尖轨与护轨横向冲击力。
Variant wheel/rail contact relationship, complicate disposal of the rails and changeable running lines are the characteristics which differentiate between the turnout and the general railway. Based on the spatial wheel/rail contact geometric relationship of the profiles between the wheel and the general track, taken account of the grade crossing disposition of the tongue rails, stock rails, wing rails, nose rails and so on, the contact traits in the switch zone and the horizontal impacted force of the guard rail and the tongue rail are simulated, and the more exact responses of the vehicle-turnout system are obtained in this paper.
