列车在道岔中的运行稳定性分析
A Study on the Running Stability of Trains on Turnouts
-
摘要: 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。Abstract: The spatial couplingmodel forrailwayturnoutsystem is improved inwhichthe vertical and lateral structure irregularities of turnouts and the variation ofwheel/rail contact geometry are taken into account. It is used to simulate the body hunting of trains and to analyze the running stability and safety of trains on turnouts.
