| 摘 要： | 针对中小跨度上承式钢板梁桥在提速时横向振幅过大的问题,提出将钢板梁桥改造成组合桥梁。应用MSC/DYTRAN大型软件对改造后的32m简支组合梁结构进行桥梁动力特性及列车走行性分析。结果表明,当运行速度在140~220km.h-1时,机车车辆的乘客乘座舒适度满足良的标准,改造后简支组合梁结构满足高速旅客列车速度小于220km.h-1的走行性要求。 |

| Abstract: | On account of the urgent need of the solution of problems of existing railway bridges arising the (lateral) amplitude over the criterion when train passing through the I type steel bridge by the increased speed, in this paper the suitable bridge type of composite beam is brought forward and the running quality of high-speed passenger train is analyzed. The finite element model is established and MSC/DYTRAN is adopted in analyzing dynamic response of the 32 m simple composite beam under the high-speed electric driven passenger train by speed of 140220 kmh~(-1). The results indicate that the rebuilt bridge satisfies the fine comfort degree and (running) quality of high-speed passenger train by the speed under 220 kmh~(-1). |
