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.

Description

technical field [0001] The invention belongs to the technical field of rail train equipment, in particular to a low-noise high-speed train pantograph based on a bionic structure. Background technique [0002] In recent years, my country's high-speed railway industry has been booming. From the well-known "Harmony" high-speed train to the newly developed "Fuxing", the speed of high-speed trains has been further improved. At the same time, the noise generated by high-speed trains is getting louder. According to the statistical analysis of high-speed train noise, when the speed of the high-speed train exceeds 300km / h, the aerodynamic noise will dominate all the noise of the high-speed train, and the pantograph part of the high-speed train is one of the main aerodynamic noise sources of the high-speed train. The transmission of high-speed train aerodynamic noise by the pantograph to the interior of the train will affect the ride comfort of the passengers inside the train, and the...

Problems solved by technology

At present, many measures have been taken in China to reduce the aerodynamic noise of high-speed train pantographs. become a serious noise source, and seriously affect the structural stability and electrical function characteristics of the pantograph; some scholars reduce the aerodynamic noise by reducing the number of pantograph rods, but this method will destroy the structural stability of the pantograph ; Some scholars have optimized the cross-section of the pantograph rod and achieved a certain noise reduction effect, but the cross-sectional size of the rod is complicated, which is not convenient for industrial application, and further research is needed
