摘要:
针对固定辙叉特殊的轨线布置及复杂的轮轨接触关系，建立固定辙叉区轮轨接触几何关系算法，分析固定辙叉区沿辙叉走行方向主要接触参数的变化规律以及各关键断面轮轨接触点变化情况。结果表明:在辙叉轮载过渡段轮轨接触参数变化规律复杂，结构不平顺变化幅值最大且波长较短；轮对横移量增加，轮轨接触几何参数增大，轮轨动力作用增强；辙叉咽喉区和轮载过渡段辙叉侧轮轨接触点变化存在突变。提出应合理设计辙叉区轮载过渡段结构参数，优化轮轨接触几何关系，进而改善列车通过时辙叉的受力性能。
Abstract:
Based on special layout of rail lines and complex wheel/rail contact relationship in rigid frog zone, a calculation method of the wheel/rail contact geometry was proposed and the changing regularity of the main contact parameters along the track line and wheel/rail contact points of key cross sections were analysed via the method. The results show that in rigid frog wheel-load transition zone, the changing regularity of wheel/rail contact parameters is complex, and the changing magnitude of structure irregularity is the highest with rather short wavelength; the higher/larger the wheelset lateral displacement is, the higher the wheel/rail contact geometric parameters are with stronger wheel/rail dynamic interaction; sudden change occurs along the longitudinal direction of frog throat area and wheel-load transition zone. It suggests that the structure parameters of wheel-load transition zone in frog be reasonably designed, the wheel/rail contact geometry relationship be optimized to improve the force performance of train passing through the frog.
