Abstract

The invention provides a vibration reduction supporting device, a railway vehicle and a vibration isolation design method for a train floor area, and belongs to the technical field of trains. The device comprises a supporting base and an elastic piece arranged on the supporting base. A vibration reduction cavity is formed in the supporting base and the vibration reduction cavity is filled with damping particles; The device also comprises a supporting plate arranged above or below the supporting base in a stacked mode, and the elastic piece is limited between the supporting plate and the supporting base. The railway vehicle comprises a vehicle body and a floor arranged above the vehicle body, and the floor is connected with the vehicle body through a vibration reduction supporting device. The invention further provides the vibration isolation design method for the train floor area. According to the vibration reduction supporting device, the railway vehicle and the vibration isolation design method for the train floor area, vibration reduction and noise reduction effects are remarkable.

Description

technical field [0001] The invention belongs to the technical field of trains, and more specifically relates to a vibration-damping support device, a rail vehicle and a vibration-isolation design method for a floor area of ​​a train. Background technique [0002] Train vibration and noise are mainly caused by factors such as wheel-rail relative movement, traction system work, personnel activities on board, air resistance, etc. It can be said that vibration and noise are everywhere. In order to improve the comfort index in the car, rail vehicle manufacturers have adopted a variety of measures, such as optimizing the bogie suspension parameters, spraying damping slurry on key parts, adding sound-absorbing material layers, etc., and achieved certain results. However, limited by factors such as existing installation structures, materials and costs, it is difficult to achieve further results. It can be seen that for urban rail vehicles, EMUs and foreseeable future higher speed m...
