A high-speed train cowcatcher structure capable of reducing aerodynamic noise is characterized in that a cowcatcher is of a variable-thickness plate-type structure, the windward end of the bottom faceof the cowcatcher is in a blunt-end arc shape and is of a horseshoe-shaped structure, and a plurality of semicircular pits are evenly distributed in the position, close to the tail end, of the bottomface of the cowcatcher. The structure provided by the invention is simple, is easy to implement on a cowcatcher, and can be arranged at the bottom of a head vehicle according to a conventional mounting mode; the windward end of the bottom surface of the cowcatcher structure is blunt-end arc-shaped, the rear end of the cowcatcher structure is rectangular or trapezoidal, four rows of pit-shaped structures are uniformly distributed on the bottom surface of the cowcatcher close to the tail end, and the thickness direction of the cowcatcher structure can be designed into different shapes accordingto modeling or other requirements.
一种降低气动噪声的高速列车排障器结构,其特征在于:排障器为变厚度的板式结构,底面前迎风端为钝头弧形,呈马蹄形结构,在排障器底面靠近尾端均匀分布若干半圆形凹坑,本发明结构简单,易于在排障器结构上实现,可以按照常规的安装方式安置于头车底部,排障器结构其底面前迎风端为钝头弧形,后端接矩形或梯形等其它形状,在排障器底面靠近尾端均匀分布四排凹坑形结构,其厚度方向可以根据造型或其它要求设计不同形状。
