Putsmier viscoelastic damping layer can be pasted or coated with appropriate viscoelastic damping material on the largest part of the extended shear strain without changing the original design of vibration reduction measures to achieve the effect of vibration reduction and noise reduction. The feasibility of this measure lies in that it does not damage the strength and working performance of the original structure, and there is no need for other special technological procedures. Therefore, this technology is extremely beneficial to the development of existing low-noise products, environmental pollution control and labor protection projects. So far, the application of damping technology involves almost all production fields.
1. Application in aerospace and aviation sectors, vibration reduction and isolation of aircraft, satellite flight cabin, missile and instruments on satellite, vibration reduction and noise reduction of aluminum flight cabin, etc. For example, the television camera of the United States outer space probe mts-77 uses a shear damping bush to attenuate the oscillation of the long extension rod of the camera. The noise reduction test was carried out by 122 factories of the Ministry of Aeronautics of China and 640 Institute of Shanghai for the domestic "Yun 12" aircraft. The damping material was used and the sound insulation was up to 28 decibels.
2. Application in Navy and navigation ships, noise reduction of various ships, especially submarines and landing hovercraft; vibration reduction and isolation and sound insulation of engine room of large ships, etc. For example, when the 1250 ton ship M / sthumpul in the UK operates, it transmits high vibration and noise to the canteen and kitchen on the upper floor. When a 5mm damping layer plus 0.8mm steel sheet is used to restrain, the sound level in the canteen decreases by 10 decibels. Pcmape damping material is pasted on 4mm thick steel plate of a warship where Shanghai 708 of China National Shipbuilding Corporation is located. The noise reduction effect is 8.7db and 7.5db respectively at lkhz and 4kHz.
3. Application in land transportation and transportation department, damping and noise reduction treatment of metro rail and wheel, sound insulation of automobile and tractor cab, vibration reduction and noise reduction of car shell structure, etc.  For example, in Britain and France, 5-layer constrained damping structure is used on Metro wheels, which has achieved noise reduction effect of more than 35 decibels. Chengdu bus factory covers 34mm damping layer on the car skin plate and top cover plate of cdk6964 bus, and pastes zn11 damping rubber plate on the inner wall of engine hood and the floor of driving area, which reduces the noise in the car from 86.4 decibels to 73.2 decibels, with obvious effect.

4. Application in heavy industry and mechanical industry, mechanical noise reduction of precision machining center and milling machine; vibration reduction and noise reduction of transmission box, transmission gear, hydraulic components and precision parts, etc. For example, gears produce medium and high frequency impulse noise when meshing is abnormal or load changes instantaneously, which can be effectively suppressed by damping treatment.
5. Applications in light industry and textile industry, such as noise reduction of washing machines, refrigerators, air conditioners, vacuum cleaners and various household appliances; noise reduction of various spinning machines and looms; damping treatment of sound equipment such as speakers, etc. For example, in j211-90 jute loom, when the shuttle is made of viscoelastic high damping material, the noise is 8 dB lower than that of UHMWPE shuttle, while the service life and fabric performance are not affected. After 17 damping measures are taken for other parts, such as leather knots and flexible plates, the noise of single machine has been reduced from 96.7 DB to 83.7 dB. For another example, the noise of Shaanxi washing machine guangshuangou brand washing machine has been reduced from 54 DB to 50.5 dB by using damping materials.
6. In the application of sports equipment, such as tennis racket, badminton racket, snowboard, etc., damping materials can make these equipment reach a stable state of small amplitude in the shortest time after being impacted.

7. The application in weapons and weapon equipment, such as armored vehicle, explosion-proof vehicle, military cross-country vehicle, tank cab sound insulation and noise reduction; turret vibration reduction and noise reduction; continuous launch weapon vibration reduction and so on, has very important damping and noise reduction effect.

8. Applications in buildings, bridges, large components, etc., such as the stability of tower cables, the application of damping vibration dampers in the interior and foundation of high-rise buildings, the treatment of damping interlayer of bridge deck, the use of air damping dynamic vibration dampers for large lifting equipment, etc. For example, in the world's second high-rise building in New York, two buildings of the world trade center with 110 floors each have more than 1000 damping isolators of 3M company of the United States. Under the wind load, the amplitude of the high-rise buildings has greatly decreased.
