Modified model-Honda XRV
Modification project: environmental protection and sound insulation upgrade of the whole vehicle.
Modification part: door+chassis+trunk+fender+hood+tailgate.
Modified material: Meite electrostatic ash drilling damping plate+Meite electrostatic cotton.
The door is the main channel for wind noise to transmit to the cab, and the thin metal plate of the door is prone to vibration and vibration noise. At the same time, the weakness of sheet metal and vibration noise will also affect the acoustic effect of the horn on the door.
The inner layer of the car door is reinforced by Meite static damping plate, which effectively reduces vibration and noise.
The damping plate is used in the outer layer to seal the redundant holes and gaps in the car door sheet metal, so as to block the transmission of external noise to the cab, and at the same time, a solid box similar to a speaker is formed between the car door sheet metal, which greatly improves the acoustic effect of the speaker.
The door trim panel is covered with a layer of Mette cotton, which enhances the sealing performance of the door, reduces the friction between the metal plate and the interior trim panel, and absorbs redundant noise.
The noise emitted by automobile chassis belongs to low-frequency noise, which is the gathering place of road noise, tire noise and engine noise. It has strong penetration, and ordinary carpet materials can not achieve good sound insulation effect.
The sound absorption of the second floor chassis is to spread a layer of sound-absorbing cotton on the basis of the first floor to absorb redundant noise and reduce low-frequency noise, wind noise and road noise.
Tail box is the main source of road noise, tire noise and low-frequency noise, so the first layer of tail box sound insulation is equipped with Mette static damping plate to enhance the thickness of sheet metal.
Original trunk line
The first floor of the trunk is soundproof.
Metersbonwe Bang Wei electrostatic cotton is installed in the trunk. The proportion of sound-absorbing cotton is very low, and the weight gain is very small when used in the car, which does not increase fuel consumption. The material is environmentally friendly, flame retardant, hydrophobic and moisture-proof.
The first floor of tailgate sound insulation adopts Meite static damping plate, which can stop vibration and enhance the thickness of sheet metal.
The second floor is covered with sound-absorbing cotton, which can block the spread of noise and absorb noise.
The first layer of fender sound insulation adopts Mette static damping board, and then adopts sound-absorbing cotton for double-layer shock absorption and sound absorption. The sound-absorbing cotton is stuffed in the gap of the fender by crimping, which can make the sound insulation effect better.

Sound absorption and noise reduction treatment of the second fender
The hood is only a thin layer of iron sheet, which will make the hood make a lot of noise, and the engine will also generate some heat to bake the paint, which will lead to the aging of the paint and wiring. Therefore, the range hood adopts double-layer sound insulation treatment, which plays a double protection role.

Automobile sound insulation has many advantages. The automobile sound insulation project can effectively eliminate and block the noise such as the roar of the engine, the vibration of the car body and the friction of the wheels, thus creating a quiet interior space and improving the comfort of the seat. After the separation of the car seat, the vibration of the car body metal is eliminated, and at the same time, it has a good sound absorption effect, making the sound clearer, richer and louder.
