Problems solved by technology

[0004] After several years of practical use, it is found that this technology has some aspects that need to be improved, mainly reflected in the fact that when the damping structure is bonded to the rail waist, the bonding strength of the individual damping structure and the rail is affected due to rust removal defects on the rail , and even the bonding of individual damping structures does not meet the standard

Embodiment Construction

[0022] The core of the present invention is to provide a damping shock absorber for rails, which has a guaranteed installation integrity rate, is less affected by derusting construction, and has a significant noise reduction effect. Another core of the present invention is to provide a steel rail comprising the above-mentioned damping shock absorber, the noise of the steel rail can be significantly reduced.

[0023] The orientation words such as inside and outside involved in this article are defined based on the rail body of the rail, and the inside is close to the outer surface of the rail, and the outer is far away from the outer surface of the rail. It should be understood that the orientation words used herein shall not limit the protection scope of this patent.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying...

Abstract

The invention discloses a steel rail and a damping absorber thereof. The disclosed damping absorber comprises a damping layer and a metal constraining board layer, as well as a magnetic material layer, wherein the damping layer, the metal constraining board layer and the magnetic material layer are laid at the rail waist of the steel rail in sequence from inside to the outside; since magnetic material layer has higher specific gravity and vibration-absorbing mass effect, the damping absorber has more obvious vibration absorbing effect; meanwhile, since the damping layer and the metal constraining board layer are closely stuck on the rail waist more reliably under the action of the magnetic attraction between the magnetic material layer and the rail body, the ineffective stickiness caused by rust and flaw removal can be effectively prevented in construction and and the potential safety hazard of falling off of the damping absorber can be eliminated, and therefore the reliability of the damping absorber is improved effectively and the denoising effect of the steel rail is increased.

Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to a damping vibration absorber for steel rails. In addition, the present invention also relates to a steel rail comprising the above-mentioned damping shock absorber. Background technique [0002] Noise is a source of environmental pollution and is extremely harmful to human health. All countries are increasing their efforts to control noise. At present, the train speed continues to increase, and the wheel-rail noise caused by the increase of train speed is on the rise. Wheel-rail noise is one of the main sound sources when trains are running, and rail vibration is the main cause of wheel-rail noise. [0003] In order to reduce the pollution of wheel and rail noise, acoustic workers and scientific and technical personnel at home and abroad have proposed treatment measures such as the use of heavy-duty steel rails, super-long seamless lines, regular grinding of steel r...
