Title:
VIBRATION DAMPING SYSTEM FOR TRACK BED, TRACK BED SLAB, TRACK BED, AND RAIL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/021443
Kind Code:
A1
Abstract:
Provided are a vibration damping system for a track bed, a track bed slab (110), a track bed (100), and a rail system. Two vibration damping forms, namely, a track bed resonator (180) and a track bed vibration damper, are provided. Since a track bed resonator (180) is used, wherein the track bed resonator (180) has a resonance board (181), which can change the inherent frequency of the track bed slab (110) and the track bed (100) as a whole, the vibration frequency of the track bed (100) and the inherent frequency of surrounding environment facilities have a frequency band difference and are not within the same resonance frequency, thereby avoiding or reducing the influence of vibration noise. Since a track bed vibration damper is used, wherein the track bed vibration damper is a vibration damping pad (190), a steel spring vibration isolator (160) or a rubber spring vibration isolator, and has an elastic unit, which can absorb and reduce vibration impact energy generated when a train travels, a rail vibration damping and noise reduction effect can be achieved. Two vibration damping modes with different principles are combined, and complementary advantages are achieved by means of the two modes, such that a more desirable rail vibration damping and noise reduction effect is achieved.
