Abstract

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
