The invention discloses a bionic outer surface structure for reducing air resistance and noise in a high-speed train, and relates to the technical field of high-speed railway traffic. The structure comprises a high-speed train shell, resistance and noise reduction mechanisms are arranged on the side face and the top of the high-speed train shell, an internal noise reduction mechanism is arranged on the inner wall of the high-speed train shell, the resistance and noise reduction mechanism comprises a lower connecting surface layer, and the bottom of the lower connecting surface layer is coated with adhesive. According to the bionic bird feather, the bionic bird feather-shaped structure protrusions are arranged on the outer wall of the upper surface layer of the bionic bird feather, the protrusions are closely arranged together, and the orderly protrusions and pits are formed in the outer wall of the upper surface layer of the bionic bird feather, so that in the running process of a high-speed train, the air flow field structure of the outer wall face of the train compartment is changed through the protrusions and the pits, resistance and noise reduction in the high-speed train traveling process is achieved, and the problem that noise in the compartment is too large in the train traveling process is solved.
本发明公开了一种高速列车减小空气阻力和降低车内噪声的仿生外表面结构,涉及高速铁路交通技术领域,包括高速列车壳体,所述高速列车壳体的侧面和顶部均设置有减阻降噪机构,所述高速列车壳体的内壁上设置有内部降噪机构,所述减阻降噪机构包括连接下表层,所述连接下表层的底部涂设有黏性胶。本发明通过在仿生鸟类羽毛上表层的外壁上设置有仿生鸟类羽毛状结构凸起,该凸起紧密排列在一起,在仿生鸟类羽毛上表层的外壁上形成有序的凸起和凹坑,在高速列车行驶过程中,利用此凸起和凹坑改变列车车厢外壁面的空气流场结构,实现高速列车行进过程的减阻降噪,避免列车行驶过程中车厢内部噪音过大的问题。
