Description

[0002] The rail vehicle floating building floor damper is a damping device installed between the floor and the car body of the rail vehicle, which mainly functions to effectively reduce the vibration and noise generated during the operation of the train through special structural design and material application, improve the riding experience of passengers, and protect the vehicle structure and equipment from damage caused by vibration. The rail vehicle floating building floor damper usually adopts a floating building structure design, i.e. a layer of elastic damping layer is arranged between the floor and the car body to form a relatively independent floating building system. When the train is running, the vibration energy generated is buffered and absorbed by the elastic elements (such as rubber springs, air springs, etc.) in the damper, thereby reducing the impact of vibration on passengers and the vehicle.
