Problems solved by technology
Due to the design characteristics of the track beams of the suspended monorail, measures such as noise barriers, interferometers, damping fasteners, and damping rails cannot be installed. Therefore, there are gaps in vibration and noise reduction measures for the design characteristics of suspended monorails in China.

Abstract
The invention provides a vibration and noise reduction method for suspended monorail traffic and a rail beam using the vibration and noise reduction method. The rail beam comprises a rail beam top plate, a rail beam web and a rail beam bottom plate. The rail beam web is vertically installed between the rail beam top plate and the rail beam bottom plate. Three are two groups of the rail beam webs and the rail beam bottom plates which are symmetrically installed at two sides of the middle line of the rail beam top plate. The inner side of the rail beam web is provided with a surface protecting plate. The surface protecting plate is fixedly connected between the rail beam web and the rail beam bottom plate. The surface protecting plate is provided with an opening. A noise reduction material is installed between the rail beam web and the surface protecting plate. The rail beam web and the surface protecting plate are flexibly connected by the noise reduction material. The rail beam has the beneficial effect of effectively controlling the operation noise level and the vibration level of the suspended monorail traffic, integrating the vibration and noise reduction, playing the vibration and noise reduction effect, and reducing the engineering investment in the greatest degree, and the structure design is compact and rational.
Description
technical field [0001] The invention belongs to the technical field of rail traffic, and in particular relates to a vibration and noise reduction measure for suspended monorail traffic and a rail beam adopting the measure. Background technique [0002] Suspended monorail is a medium-capacity rail transportation system in which vehicles and special rail beams are combined to operate in one. Together with the subway system and the light rail system, it constitutes three categories of urban rail transit. The suspended monorail (air train) system has the characteristics of technology, ecology and high efficiency. The system adopts electric traction and does not produce exhaust gas pollution. Under the same transport capacity, compared with public transportation (highway), it can effectively reduce urban exhaust emissions and noise pollution, and can greatly reduce vehicle exhaust emissions, which will have a significant effect on improving urban air environment, but trains The...
