摘要
本文建立了轨道结构空间自由振动模型。运用有限元理论,分析了既有线路在不同支承条件下的固有频率和固有振动特性。结合车辆蛇行运动稳定性的讨论,探讨了影响提速线路横向稳定性的因素,提出了加强措施。
In this paper,the space free vibration analysis model for track structure is established. By means of the finite element theory, the inherent frequencies and vibration characteristics for existing rail line under different supporting conditions are analyzed. Combining the discussion of stability of vehicle snake movement, the effects on transverse stability of inc reasing speed rail line are studied and the enhanced measurements are presented.
