Abstract

The invention relates to a rail damper with a built-in bottom plate and a design method thereof, the damper comprises a bottom plate, a roof, a rubber layer, and an elastic clasp of a rail pressed together with the roof, the damper is characterized in that the bottom plate is placed in the roof and is in vulcanization connection with the roof through a rubber layer. The vulcanized joint surfaces of the bottom plate and roof are both inclined planes, and the bottom plate is provided with anchoring mounting holes for being fixedly connected with a sleeper. The bottom plate is arranged in the roof, and the installation position of the rail damper is designed in the inner part of the product to reduce the requirement for the installation size of the sleeper, which is suitable for the connection of a small sleeper and a rail damper, thus improving the transverse stiffness of the rail damper. The rigidity of the rail damper can be adjusted, the probability of permanent deformation of the rubber layer can be reduced, the reliability of use of the rail damper is improved, the vulcanization molding is simpler, the requirements of mold, technology and equipment are lower, and the transverserestraint performance of the rail damper is improved. The safe driving performance of small curve radius sections is improved.

Description

technical field

[0001] The invention relates to a bottom plate built-in track damper and a design method thereof, which is used in track sections requiring vibration and noise reduction in various subways and urban light rails, connects rails and sleepers, and effectively isolates vibration and reduces noise. Background technique

[0002] With the development of rail transit, more and more cities have invested in the construction of urban rail subway systems. Different design concepts make the types of rails various, which also puts forward better requirements for the adaptability of rail shock absorbers. . Rail shock absorbers can realize load bearing, vibration reduction and ensure driving safety in rail transit lines. In order to save the limited space in the rail transit tunnel, it is required that the rail shock absorber must have appropriate dimensions while meeting the vibration reduction requirements. Rail shock absorbers are connected to the subgrade and rails thr...
