Description
Technical field
The utility model relates to vibration and noise reducing device, especially a kind of no-top plate track train air-conditioning vibration and noise reducing device.
Background technology
At present, traffic department improves constantly the requirement of domestic track train loss of weight noise reduction, and during the interior environment system on-line operation of track train, the noise of its generation will be delivered to inside, train guest room, influences the traveling comfort of passenger in the train guest room.
In addition, the transport capacity of train is directly connected to energy-saving and cost-reducing.At present, transport capacity, the reduction tare of part rain model in order to improve self will be positioned at the top board of locating under the train body air-conditioning unit and remove, thereby reduce the weight of car body.But so also just more strict requirement has been proposed for the noise reduction of train air-conditioning unit." no-top plate " train is when operation, and the noise of its air-conditioning unit inner blower and compressor is directly delivered to train inside by the base plate of air-conditioning unit, thereby directly has influence on passenger's traveling comfort.Therefore, in order to improve the traveling comfort of passenger in the no-top plate train, reduce the noise that the air-conditioning unit is delivered to inside, guest room, it is very urgent to study a kind of air-conditioning unit that can satisfy no-top plate track train operating needs.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, with low cost, can effectively reduce the noise that the air-conditioning unit is delivered to inside, train guest room, improves passenger's traveling comfort.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of no-top plate track train air-conditioning vibration and noise reducing device comprises the damping mucilage layer that is sprayed on the air-conditioning unit base plate, pastes at the sound insulation flaggy below the damping mucilage layer and is positioned at backplane level below the sound insulation flaggy; Described backplane level is captiveed joint with the air-conditioning unit by the staking structure.
Between damping mucilage layer and sound insulation flaggy, also be adhesive with first heat-insulation layer; Below backplane level, be adhesive with second heat-insulation layer.
The thickness of described damping mucilage layer is 2mm; The thickness of described first heat-insulation layer is 6mm, and its material is rubber; The thickness of described sound insulation flaggy is 2mm, and its material is rubber; The thickness of described backplane level is 1mm, and its material is stainless steel sheet; The thickness of described second heat-insulation layer is 9mm, and its material is rubber.
Above-mentioned every layer of structure all satisfies the requirement of fire prevention, loss of weight and noise reduction.
The beneficial effect that adopts technique scheme to produce is:
By the damping rubber cement is painted on the air-conditioning unit base plate, can effectively reduces the noise that air-conditioning unit back plate vibration produces, thereby reduce the noise that is delivered in the train guest room.By using the damping rubber cement and being used insulation board and panel, heat-insulation layer and backplane level, form five layer composite structures, this structure can effectively weaken the transmission of noise, reduce air-conditioning compressor, fan noise is delivered to inside, guest room by the unit base plate, the noise that the air-conditioning unit produces is by can effectively satisfying the vibration and noise reducing requirement in the no-top plate train guest room behind the weakening of this five-layer structure.The utility model utilizes the physical property of its particular structure and damping material, finely must realize the vibration and noise reducing effect, and is not only simple in structure, and with low cost, effectively reduced the noise of inside, train guest room, improved passenger's traveling comfort.
