不规则是影响车轮栏杆接触几何学关系的一个关键因素。在这份报纸，我们计算了接触指向典型的节的车轮栏杆并且获得了与踪迹行方法的车轮栏杆几何学关系的纵的变化。关键栏杆节的侧面被立方的花键曲线匹配，并且形状插值在非控制的节被认识到。结果证明在典型的节与轨道排列的增大逐渐地增加的各个的转动角度不规则。当凸缘接触发生时，转动角度戏剧性地增加。向开关栏杆的合适的轨道排列不规则改进结果的结构不规则。

英文摘要：

The irregularity is a key factor affecting the wheel-rail contact geometry relationship. In this paper, we calculated the wheel-rail contact points at typical sections and obtained the longitudinal variation of the wheel-rail geometry relationship with the trace line method. The profile of the key rail sections was matched by cubic spline curve, and the shape interpolation was realized in non-controlling sections. The results show that the roll angles at each typical section increases gradually with the enlargement of track alignment irregularity. When the flange contact occurs, the roll angle increases dramatically. Proper track alignment irregularity towards the switch rail improves the structure irregularity of the turnout.
