Optimization Analysis of Height and Distance for Shelter Wind Wall of High Speed Railway


Article Preview

Shelter wind wall is one of the most effective devices to reduce crosswind loads acting on trains. The height of the wall and distance between the wall and the center of railway are important factors for design and construction of wind wall. Since the wall design is related to many factors, such as train speeds, transverse wind speeds, types of the wall and so on, up to now, there are still different judgment methods in the optimal height and distance of the wall to get minimum aerodynamic forces on the train. Based on numerical analysis methods of three-dimensional viscous compressible aerodynamics equations, aerodynamic side forces and rolling moments acting on the train are analyzed. With 275 calculation models, include the straight and different radius curve railway with different heights and distances of shelter wind wall, the aerodynamic side forces and rolling moments are calculated. Simulation results show that the optimal height and distance of the wall are not the same during in straight and curve railway. And the direction of aerodynamic side force and rolling moment acting on the head and rear train may be different. The change trends of transverse forces (moments) with the height and distance of the wall are also different.
