As a venue for the 2022 Winter Olympic and Paralympic Games, National Alpine Skiing Center is located on Xiaohaitou Mountain in Beijing’s Yanqing district, where strong winds occur frequently. To reduce impact of competition, windbreak fences have been installed ski area. determine effect stability beside slope alpine skiing center, numerical simulation method was used to study performance 3.7 ...

Under strong winds, the effect of sudden windbreak transition (WT) on high-speed trains is severe, leading to a deterioration train aerodynamics and yawing motion car body. To address these problems, based specific geometric conditions derived from Xinjiang railway, first, impact WT reasons for changes in aerodynamic forces were determined by flow structural analysis. Furthermore, multibody sys...
