By running the program based on vehicle-railcoupling dynamics, compute the dynamic response of elastic sleeper ballasted rail and common sleeper ballasted rail under same working condition.
Based on random rail roughness and vehicle-bridge coupling element, a method is proposed for calculating random vibration of long span Bridges under moving vehicles in this paper.
