Background
With the continuous development of urban rail transit and overhead lines, the environmental vibration induced by the rail transit and the overhead lines also increasingly affects the work and life of urban residents. Vibrations in the train and track structure are caused by the train's own vibrations, wheel-track interactions and track irregularities, which propagate outward through the surrounding strata, further inducing secondary vibrations and noise pollution in nearby underground structures and adjacent buildings.
Researches show that environmental vibration caused by rail transit and overhead lines is mainly vertical vibration, and has great influence on the safety of buildings which are in close range for a long time. Meanwhile, in industrial production and scientific research, some equipment and instruments are very sensitive to tiny vibration, and the tiny vibration can also interfere the normal operation of the equipment and instruments.
At present, the control means and technology of environmental vibration are not mature enough, and the damping device in the prior art has the following defects:
1. the structure is complicated, and the vertical height of the device is large.
2. It is not possible to provide both vertical load bearing capacity and damping.

the top of the accommodating cavity is open; the supporting part is inserted into the accommodating cavity and is contacted with the top of the elastic cushion.
In the above scheme, the bearing part has two functions at the same time: firstly, the load transferred by the upper seat plate and the lower seat plate can be borne; secondly, the elastic cushion can vertically reduce vibration and consume energy.
Preferably, the elastic pad is a rubber pad.
Preferably, a sealing device is arranged between the inner wall of the accommodating cavity and the outer wall of the supporting part. The sealing means may be a sealing ring, for the purpose of protecting the elastic pad.
In a specific scheme, the damping system is a rubber spring damping system and comprises a guide rod arranged between an upper seat plate and a lower seat plate and a composite rubber spring sleeved on the guide rod;
the composite rubber spring comprises a spring sleeved on the guide rod and a rubber layer vulcanized with the spring.
In order to prevent aging, a chloroprene rubber protective layer is arranged on the outer surface of the composite rubber spring.
In another specific scheme, the damping system is a rubber spring damping system and comprises a guide rod arranged between an upper seat plate and a lower seat plate and a hollow high-damping rubber sleeve sleeved on the guide rod;
the inner wall of the high-damping rubber sleeve is provided with mounting grooves at intervals for mounting springs, springs are arranged in the mounting grooves, and the guide rods penetrate through the central shafts of the springs.
In order to prevent aging, a chloroprene rubber protective layer is arranged on the outer surface of the high-damping rubber sleeve.
Preferably, the spring is a disc spring.
Further, the bearing part is arranged in the middle area of the upper seat plate and the lower seat plate, and the damping systems are uniformly distributed around the bearing part.
The invention has the following remarkable effects:
1) when elastic deformation occurs, the rubber spring damping system and the elastic cushion are used for simultaneously consuming energy or reducing the vertical vibration of the structure.
2) The design of the bearing part enables the device of the invention to bear vertical bearing capacity and reduce vertical vibration of the structure.
