| Abstract: | Regarding the vehicle and the bridge as a combined vibration system and using research methods of bridge structure dynamics and vehicle dynamics,a vehicle/bridge interaction model of Wuhan Tianxingzhou Yangtze-River Bridge was established.Based on the reasonable train runability evaluations,the train running safety and passenger riding comfort with freight trains and high-speed trains across the bridge were especially studied.The applicability of long-span rail-cum-road cable-stayed bridge for freight train... |
