The Role of Sound-absorbing Padding in Automobiles

Auxiliary with sound-absorbing cotton. At the same time, as the temperature of the water tank increases, it may experience prolonged operation. At this time, the insulation effect of the sound-absorbing cotton can play a good role, because it can avoid accidents caused by the high temperature of the engine directly transmitted to the engine hood after starting, and also effectively avoid the impact of fog on the visibility of the engine hood on rainy days. So, where is the sound-absorbing cotton specifically located?

After the sound insulation of the car door, due to the effective filling of the cavity inside the door, the sound of closing the door becomes dull and steady, sounding very comfortable, and there is no longer the sound of breaking gongs,

After the sound insulation of the front and rear covers, firewall, and bottom plate, the harsh valve smell of the engine is filtered out, leaving only low overall speed sound and underfoot vibration. After the temperature of the water tank rises, the tachometer drops to 1000 revolutions per minute. When driving at full speed, only by carefully feeling the interior of the car can one hear the engine running and almost feel like it's stalling; At this point, when you turn on the speaker again to enjoy music, you will find a significant improvement in the effect.

3. Reduce and effectively alleviate chassis metal fatigue, extend vehicle lifespan,

The reason for metal fatigue is the uneven internal structure of the metal, which leads to unbalanced stress transmission and some areas become stress concentration zones. At the same time, there are many small cracks in the defects inside the metal. Under the continuous action of force, cracks will become larger and fewer materials capable of transmitting stress will be available. Metal components will be completely damaged until the remaining parts cannot continue to transmit loads.

The above is a detailed introduction to the specific functions of sound-absorbing cotton. It is inevitable that the car chassis will experience hundreds or even thousands of vibrations every day, which means it is prone to metal fatigue, so attention should be paid. After all, the chassis plays a significant role in considering the safety of car driving. If the sound insulation treatment is not good, there will definitely be problems. Therefore, using sound-absorbing cotton to adhere its excellent sound-absorbing and shock-absorbing effects to the chassis can reduce chassis vibration and eliminate metal fatigue.
