Abstract
During recent years, with the rapid development of high speed railway construction and the largely improved train speed, its aerodynamic problem has been paid more and more attention to. Particularly under the gust, the train running conditions are deteriorated further so that the safe operation faces the serious challenge. In this paper, the two-dimension computing fluid dynamics numerical simulation on its aerodynamic characteristic has been made about the high speed train running on double line viaduct in the windward under the gust. The simulation results show that there is obvious gust effect when the acceleration is changed for loading side linear wind spectrum. The transverse gust will have distinct influence on the side force, while it is relatively weak for the lifting force. The numerical simulation computing method has been explored by two-dimension field calculation and it can offer the engineering reference for succeeding three-dimension numeration.
