单轨列车与折线道岔的几何学关系

Geometric Relation between Monorail Train and Articulated Turnout

跨坐式单轨列车在通过折线型道岔时,水平轮会产生一定的横向压缩,导致列车进行大幅度地左右摆动。水平轮变形量的大小取决列车和道岔的相关参数,影响着列车的平稳性和水平轮使用寿命。通过几何学仿真计算,得到了水平轮所产生最大变形量的理论数值,并分析出了通过过程中水平轮的变形趋势:即在跨坐式单轨列车通过折线道岔时,水平轮会在一些时候产生更大压缩变形;而另一些时候则可能离开轨道梁侧面,恢复到自由状态。

The horizontal wheels of monorail train will be compressed and their size will change when the train is passing through an articulated turnout, that will make the train swings violently. The size change of the horizental wheels depends on the parameters of both the train and the turnout. This paper calculates the maximum size change of horizontal wheels and analyzes the paterns of the size change, aiming to find the dynamics peculiarity of the monorail train bogie.
