The invention discloses a low-noise high-speed train pantograph based on a bionic structure. The train pantograph comprises pantograph corners, a pantograph head bracket, contact carbon sliding plates, a bracket rod, an upper arm rod, a lower arm rod, a bottom frame and an insulator, the insulator is arranged at the bottom of the bottom frame, one end of the lower arm rod is arranged on the bottomframe, and one end of the upper arm is hinged to the other end of the lower arm rod. The pantograph head support is hinged to the other end of the upper arm, the carbon sliding plates are arranged atthe two ends of the pantograph head support, the pantograph corners are fixed to the two ends of the carbon sliding plates, and the support rod is arranged on the pantograph head support and arrangedbetween the carbon sliding plates. The shape of the pantograph head rod piece of the pantograph is improved based on the bionic structure, aerodynamic noise of the pantograph head is effectively controlled, it is guaranteed that structural stability and electric power functional characteristics of the pantograph are not affected, and interference of the aerodynamic noise of the pantograph of thehigh-speed train on the surrounding environment is reduced.
本发明公开了一种基于仿生结构的低噪声高速列车受电弓,包括弓角、弓头支架、接触碳滑板、支架杆、上臂杆、下臂杆、底架和绝缘子,所述绝缘子设置在底架底部,所述下臂杆的一端设置在底架上,所述上臂的一端铰接在下臂杆的另一端,所述弓头支架铰接在上臂的另一端,所述碳滑板设置在弓头支架的两端,所述弓角固定在碳滑板的两端,所述支架杆设置在弓头支架上,且设置在碳滑板之间。本发明基于仿生结构对受电弓弓头杆件形状进行改进有效地控制了弓头气动噪声,保证了受电弓结构稳定性与电力功能特性不受影响,减轻了高速列车受电弓气动噪声对周边环境的干扰。
