Embodiment Construction

[0012] After placing the overall shape of the sound barrier on the sound barrier assembly, make the concave face the high-speed railway. When the high-speed train passes, the running wind acts on the concave surface of the overall shape (1) and is immediately replaced by the continuous convex-concave arc surface of (2). Line reflection or projection decomposition to avoid reflection back to the car body; pressure waves cause the continuous convex and concave arc surface of (2) to produce elastic deformation vibration, thereby absorbing energy, and at the same time, control the driving wind to transition through the diffraction arc (3), so that It vibrates with the air layer behind to further disintegrate the energy of driving wind and noise; when the seasonal temperature changes, the continuous convex and concave arc surface can also produce elastic deformation to avoid stress damage caused by linear deformation.

Abstract

The invention relates to a sound barrier panel device for disorganizing the high speed train running wind energy. The whole structure is formed by a sheet steel in a stress arc shape, a sheet steel in a disorganized small arc shape and a sheet steel in a stream guidance arc shape. High speed train running wind acts on a whole concave face, the concave face is formed by continuous convex-concave arc surfaces with different curvature radii, the acting force of the running wind can be disorganized to the greatest degree, then diffracted rays at the top of a sound barrier are made to be of a sheet steel arc structure, suddenly-changed propagating geometric routes of the running wind are avoided, meanwhile, vibration of the diffraction sheet steel arc structure and an air layer at the back is caused by the running wind, and energy of the running wind and energy of noise are further disorganized.

Description

[0001] The invention discloses a sound barrier panel device for disintegrating the running wind energy of a high-speed train. In particular, the sound barrier and the running wind force bearing surfaces are curved surfaces with different curvature radii, which can quickly decompose the moving direction and energy of the running wind. technical field [0002] Noise control in the field of environmental protection. Background technique [0003] At present, the sound barriers of high-speed railways generally use H-shaped steel as the column, so that the web of the H-shaped steel is perpendicular to the railway, and the two wing plates are parallel to the railway; a metal sound-absorbing box is inserted between the two columns; the box faces the side of the railway. The working surface is made of perforated aluminum alloy plate, and the back is made of integral aluminum alloy plate to form a surface perpendicular to the ground to withstand the force of the high-speed train runnin...
