Description

Track pressing plate vibration damper for urban track

Technical Field

The utility model relates to a track technical field, more specifically relates to a track clamp plate vibration damper for urban rail.

Background

The subway is a form of railway transportation, and refers to an urban rail transit system which is mainly operated underground, namely the underground railway or the underground railway is short for description; many such systems may be switched to ground or elevated sections of road in areas outside of urban centers in order to fit the building environment and take into account construction and operating costs. The subway is an urban rail transit system which covers the exclusive right of way, high density and high traffic volume under various underground and overground roads in urban areas, and the Taiwan subway in China is called as 'rapid transit'. In addition to underground railways, elevated railways or railways laid on roadways are also included. Therefore, the subway is exclusive to the right of way and has no level crossing, which is also the fundamental sign that the subway is distinguished from the light rail traffic system. The earliest (and first) subway in the world was the metropolitan subway in london, england, and was established in 1863. In China, with the progress of modernization, the trend of large-scale development of a traffic system is extremely rapid.

The environmental vibration induced by subway operation can interfere the normal life of people, make people feel uncomfortable, even influence the study and rest of people, and the vibration is internationally classified as one of seven environmental hazards. The induction of strong ground wave and rail vibration by high-speed trains has attracted much attention by foreign scholars and railway companies.
