Bottom plate built-in rail shock absorber and its design method, including bottom plate, top plate, rubber layer and elastic clips that cooperate with the top plate to press the steel rail, characterized in that the bottom plate is placed in the top plate, and vulcanized by the rubber layer and the top plate Connection, the vulcanized connection surfaces of the bottom plate and the top plate are sloped, and the bottom plate is provided with anchor holes for fixing with sleepers. In the present invention, the bottom plate is arranged in the top plate, that is, the installation position of the track damper is designed inside the product, and the requirement for the installation size of the sleeper is reduced. Lateral rigidity, realizing the adjustable stiffness of the rail shock absorber, reducing the probability of permanent deformation of the rubber layer, improving the reliability of the rail shock absorber, simpler vulcanization molding, lower requirements for molds, processes, and equipment, and improving The lateral restraint performance of the rail shock absorber improves the safe driving performance of the road section with small curve radius.
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...
