摘要
将地下轨道振动模型分为两个子模型:列车荷载及轨道模型。基于ANSYS分别建立了整体道床、弹性短轨枕、橡胶支承浮置板轨道及钢弹簧浮置板轨道二维有限元模型。通过模态分析、谐响应分析及瞬态分析对不同轨道进行了计算,得出了一些有益的结论供地下轨道形式的选取作为参考。
This paper divides the vibration model of underground orbit into two sub models ： train load and track model. Based on ANSYS, the two dimensional finite element model of the whole ballast bed, the elastic short sleeper, the rubber bearing floating plate track and the steel spring floating plate track are established respectively. Through modal analysis, harmonic response analysis and transient analysis, different tracks were calculated, and some useful conclusions were drawn for reference to the selection of underground track form.
