Title:
SHOCK WAVE WEAKENING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/047969
Kind Code:
A1
Abstract:
A shock wave weakening system, comprising a buffer device (100), a plurality of through holes (200) being provided in the buffer device (100), and an outer side of the buffer device (100) being used for being connected to an inner wall face of a tunnel (400) or a pipeline. Due to the high-speed motion thereof, a motor train unit generates shock waves in the tunnel (400) or the pipeline, and the shock waves penetrate the through holes (200) of the buffer device (100) and are gradually absorbed and weakened by means of the through holes (200), such that the shock waves cannot accumulate after being reflected by the inner wall face of the tunnel (400) or the pipeline, the influence of the shock waves on the motor train unit is further weakened, and the driving safety of the motor train unit is ensured.
