深圳地铁道床动载荷分析

Analysis on Dynamic Loads on Ballast of Shenzhen Subway

摘要: 根据车辆轨道模型,从频域和时域两方面分析了深圳地铁道床动载荷,得出了道床动载荷传递函数,根据传递函数找出了最不利波长,并参照铁路对短波不平顺管理标准,得到了道床最大动载荷。

Abstract: According to the model of coupled vibration of vehicle and tracks, the dynamic loads of ballastof Shenzhen subway are calculated in both frequency and time domains. The relationship between dynamic loads and track irregularitywavelengths are obtained. The maximumdynamic load is about80 kN/mmatthe worst frequency, about 62 Hz
