中文摘要	It is also very important to improve resistant capabilities of wind resistance and structural stability of the windbreak while reducing train aerodynamic load. This article proposes a new type of windbreak with double-layer structure forming a cavity chamber with hole for energy dissipation of crosswind. Numerical simulation was used to analysis the wind protection effect of two kinds of windbreak and their own wind-resistance performance. The results showed that the two types of windbreaks can significantly reduce the train aerodynamic load under the action of crosswind, and the force act on the windbreak with cavity chamber structure is small than on another one with single layer structure. The new windbreak has better effect in aerodynamic load shedding for the train, stronger resistant capabilities of wind resistance and safety of structure. This new windbreak with cavity chamber will provides useful references for design of the wind protection system for high speed train. © 2013 Taylor & Francis Group.
