架桥机跨武广高速铁路时的抗风稳定性研究
Research on wind-resistance stability of the bridge-erecting machine acrossing the Wuhan-Guangzhou high-speed rail
摘要
Abstract
Based on the CFD software Fluent and the dynamic mesh technology, the programs for the UDF trains route procedures were wrote. The high-speed trains crossing through the bridge-erecting machine was simulated in different motion forms under the situations of strong crosswind. Firstly, the impact loads and aerodynamic force created by strong crosswind and the train-wind of the launching nose were calculated. Secondly, the speed and the pressure distribution were received through the monitoring points of the launching nose sections. Finally, the paper studied the aerodynamic effects in various conditions of train motion forms on the launching nose sections, which provides a valuable reference and recommendation for bridge constructors in evaluating the safety stability of the bridge-erecting machine.关键词
