考虑道岔结构引起的竖向与横向不平顺以及轮轨接触关系的变化,将道岔区内轮轨系统空间耦合振动分析模型进一步完善。该模型用以模拟列车经过道岔时的蛇行运动,并分析了列车的平稳性与安全性。
Considering the vertical and horizontal irregularities caused by the turnout structure and the changes of the wheel-rail contact relationship, the space coupling vibration analysis model of the wheel / rail system in the turnout area is further improved. The model is used to simulate the meandering movement of trains passing the turnout, and the stability and safety of the train are analyzed.
