Abstract
The utility model relates to a noise-reducing damping structure for a side wall of a rail train, and belongs to noise-reducing damping structures for side walls of rail trains. The mount pad and the peripheral fixed connection of aluminium alloy casing, the parallel placing of shock attenuation capsule is in the aluminium alloy casing, and the apron passes through bolt and aluminium alloy casing fixed connection. The structure is novel, and the vibration generated outside the vehicle body can be absorbed to reduce noise and the vibration generated inside the vehicle body can be absorbed to reduce noise; a series of noises such as wind resistance generated outside in the running process of a train are transmitted to the interior of the train body through vibration, when the noises are transmitted to the side wall, part of energy is consumed by the movement of damping particles in the internal damping capsules and is absorbed by the damping plastic film, the vibration generated by equipment such as a train body engine and transmitted by a train frame is also consumed and absorbed, and the noise of the train can be reduced by 3-4 dB through testing.
Description
Technical Field
The utility model belongs to a noise-reducing and shock-absorbing structure of a side wall of a rail train.
Background
With the development of science and technology, the requirements of people on noise reduction and shock absorption are higher and higher, and the requirements of people on noise cannot be met by the common rail train at present. In the train operation process, the noise sources mainly have two points: the body itself and the outside.
Although the side walls of the train are subjected to noise reduction treatment at present, the noise reduction effect generated by the adopted structure cannot reach a satisfactory degree. The train side wall is made of traditional materials such as: carbon fiber cotton, rock wool, ceramic fiber cotton and the like, and the materials can only reduce noise by sound absorption effect and can not solve the noise from the source. The side wall part is connected by metal, the traditional material can only absorb partial noise, and partial noise is transmitted to the indoor through metal and a rigid structure. The vibration cotton material generated by the vehicle body can not be absorbed and can also be transmitted to the indoor to generate noise.
Disclosure of Invention
The utility model provides a noise-reducing damping shock absorption structure for a side wall of a rail train, which aims to solve the problem of poor noise-reducing and shock absorption effects of the side wall of the rail train.
The technical scheme adopted by the utility model is as follows: the aluminum profile shell damping device comprises a mounting seat, a bolt, a cover plate, a damping capsule and an aluminum profile shell, wherein the mounting seat is fixedly connected with the periphery of the aluminum profile shell, the damping capsule is parallelly placed in the aluminum profile shell, and the cover plate is fixedly connected with the aluminum profile shell through the bolt.
The structure of the damping capsule is as follows: the modified damping plastic film bag is filled with shock absorption particles.
The shock absorption particles adopt steel balls with the diameter of 1 mm.
The damping capsule partition plate is arranged in the aluminum profile shell.
The utility model has the advantages that the structure is novel, and the vibration generated outside the vehicle body can be absorbed to reduce noise and the vibration generated inside the vehicle body can be absorbed to reduce noise; a series of noises such as wind resistance generated outside in the running process of a train are transmitted to the interior of the train body through vibration, when the noises are transmitted to the side wall, part of energy is consumed by the movement of damping particles in the internal damping capsules and is absorbed by the damping plastic film, the vibration generated by equipment such as a train body engine and transmitted by a train frame is also consumed and absorbed, and the noise of the train can be reduced by 3-4 dB through testing.

Detailed Description
The aluminum profile damping device comprises a mounting seat 1, a bolt 2, a cover plate 3, a damping capsule 4 and an aluminum profile shell 5, wherein the mounting seat 1 is fixedly connected with the periphery of the aluminum profile shell 5, the damping capsule 4 is placed in the aluminum profile shell 5 in parallel, and the cover plate 3 is fixedly connected with the aluminum profile shell 5 through the bolt 2;
the structure of the shock absorption capsule 4 is as follows: the modified damping plastic film bag 401 is filled with shock-absorbing particles 402;
the shock absorption particles 402 are steel balls with the diameter of 1 mm;
the inside of the aluminum profile shell 5 is provided with a damping capsule partition plate 501.
Principle of operation
The damping rubber is arranged in the side wall of the railway train by gluing or riveting, a series of noises such as wind resistance generated outside are transmitted to the inside of the train body by vibration in the running process of the train, the damping rubber absorbs vibration energy when being transmitted to the side wall, the vibration energy is consumed by the movement of the damping particles in the internal damping rubber bag and the damping plastic film absorbs part of the energy, and meanwhile, the vibration generated by equipment such as a train body engine is transmitted to the damping rubber film by the train frame for consumption.
