Sound insulation wall of railroad vehicle

鉄道車両の遮音壁

Abstract

PROBLEM TO BE SOLVED: To provide a sound insulation wall of a railroad vehicle capable of reducing the noise of a power collector of the railroad vehicle traveling at a high speed. SOLUTION: In the sound insulation wall 1 of the railroad vehicle provided so as to cover both sides of a power collector mounted on an upper part of the railroad vehicle 2 in the advancing direction of the railroad vehicle, the sectional shape of the sound insulation wall 1 when viewed in the advancing direction of the moving vehicle is formed so as to be expanded in the separating direction from a center part of the railroad vehicle as the height is increased in an upper part, and expanded in the separating direction from the center part of the railroad vehicle as the height is decreased in a lower part, and a section of at least one end of a front side or a rear side when viewed from the side in the railroad vehicle advancing direction is corrugated with a projecting shape and a recessed shape being arranged alternately.
