If we hit an iron pot directly, it will make a very crisp metal knocking sound, and if we spray a thick layer of rubber inside the iron pot, we will find that the knocking sound becomes very muffled and the sound is noticeably softer.

The rubber coated on the inside of the iron pot is the damping layer. The same is true in the automotive field: the inner layer of the automotive steel plate is coated with some soft materials to achieve the effect of noise reduction and sound insulation.

That's where automotive damping pads come in. It can effectively reduce the vibration of the automobile steel plate and achieve the effect of quiet in the car.

Usually the more common car damping material is asphalt sheet, because the asphalt processing process is inevitably mixed with some impurities, and these chemical impurities have a smell, so many car damping asphalt sheet itself has a smell.

The damping plate is actually to prevent energy loss, in the car, it is generally the effect of heat insulation, sound insulation and shock absorption, in the car body, attached to the body steel plate, it is generally not easy to see.

The damping plate is the first time I have heard of it, and I have generally heard of the damping glue, which is pasted on the inside of the sheet metal, changing the resonance frequency, and playing the role of sound insulation and shock absorption. Improvement of the body NVH....

The damping plate of the car is placed or sprayed with damping rubber plate in the front wall, side wall, trunk, top cover and other parts.

Purpose: In order to provide a quiet and comfortable environment for car drivers and passengers, and prevent the transmission of noise, heat and vibration generated by the engine during the driving process of the car, installation: In the process of painting and coating the automobile body, most of the damping rubber plates currently used are asphalt-based after the primer is dried, and the cold resistance, elasticity and aging resistance of the product are poor, and contain harmful substances to the human body.

The damping gasket in the car is mainly distributed on the metal plate with a large internal area and a relatively flat shape, and the damping sheet is a component used to reduce the vibration in the car and improve the comfort of the cabin. The function is to use its viscoelastic properties to dampen the vibration generated on the metal plate, and at the same time affect the natural frequency of the body that produces noise, so as to improve the noise generated when the vehicle vibrates, so as to achieve the purpose of sound insulation and noise reduction.

In the carriage, a layer of tough damping materials is pasted for shock resistance, noise reduction and heat insulation, which are mainly distributed around the carriage, such as the floor under the seat, the tunnel floor, the wheel cover, and the spare tire groove. The vast majority of family cars use damping gaskets in the car, and each car uses damping gaskets in about 8-12 places, with a total area of more than 3 square meters. If all asphalt damping gaskets are used, the amount of asphalt used can be up to 10 kg.

Damping is basically a resistance force that is opposed to the speed of movement. This property causes it to only consume energy, not release it.

This is done in order to deplete the energy generated by the vehicle's vibration as quickly as possible. lest the car keep bouncing like a trampoline.

There are plastic parts, but there are not many, and the wheel lining plate is plastic

There is a plastic piece, but not a lot.

Mainly concentrated in the cab, the interior parts of the cab such as the door panel or something are ABS blister parts, the instrument panel is fiberglass, some are ABS blister parts with foam layer, and some small interior parts are injection molded parts, and the specific materials are not clear.

There are also some bumpers on the body, some are fiberglass, some are injection molded parts, and the specific material is not very clear.

Some battery box lids are also injection molded, and the specific material is not clear.

Yes, but not many;

When the car is hoisted, you should be able to see it (fenders.

Generally, it is an injection molded part, and there are many materials, such as PE.

Your question is a bit general, which model are you talking about, and when you say chassis, do you mean the suspension and the driving system, or do you mean the underbody?

Gearbox, front axle, rear axle accessories have rear axle body with mounts, spring device, wheels, hand control and foot lever device accessories have shift control device.

The automobile chassis is composed of four parts: the transmission system, the driving system, the steering system and the brake system.

The role of the chassis is to support and install the automobile engine and its various components and assemblies, form the overall shape of the car, and accept the power of the engine, so that the car can move and ensure normal driving.

The power emitted by a car's engine is transmitted to the driving wheels by the drive train. The drive train has the functions of deceleration, speed change, reversing, interrupting power, inter-wheel differential and inter-axle differential, etc., and works with the engine to ensure the normal driving of the car under various working conditions, and has good power and economy.

It should be the suspension and shock absorbing springs, plus different designs can improve the comfort of the car, sitting over the ditch is like crossing a flat road, not shaking like a bus.

1. The buffer system of the chassis is mainly springs, shock absorbers, and rubber (hydraulic) gaskets.

The chassis of Japanese cars is light and fast, and Germany, the United States and France are more calm, which is mainly determined by the performance parameters of shock absorbers and springs.

If the spring shock absorber is damped, the car will look tougher, so a lot of impact will be transferred to the liner and other structures of the car chassis, which will throw less jump, shake less, and give people a stable feeling. However, this damage to the chassis is great, so the decline in used car driving products of German and Japanese cars of the same age is much more serious. The damping is small, and it will be easier to bottom out when the big impact occurs, so it feels like the chassis is thin, but the usual small impact can basically be digested by the spring shock absorber, which is conducive to the longevity of the chassis system.

There are wheels, body, flanges, brackets, fuel tanks, engines, glass windows, windshields, rearview mirrors, etc. There are various processes that use steel plates, iron plates, stainless steel plates, aluminum alloys, rubber, and plastics.

The structure of the car is roughly divided into chassis, body, interior, power system, and suspension system.

Just buy a new car to spray a chassis armor, the best heat and sound insulation is the rubber type, ** that Lei Dun AC rubber chassis armor is good, many of our riders are using that!

The chassis is soundproofed, if you want to focus on processing, you can paste 3 layers, which are:

Paste the damping sound insulation and vibration blocking pad first.

Then paste damping sound insulation sound absorption cotton.

Finally, car interior sound-absorbing cotton.

Like the calm and powerful ** physical store Changsha new field car sound insulation, the general standard construction is to first paste a layer of damping sound insulation and vibration damping pad rubber strips, and then paste a layer of damping sound insulation sound absorption cotton to do double-layer sound insulation, which will not have a very good effect.

If you just think that the chassis needs to be soundproofed, then you only need to paste a layer of soundproofing panels, if your requirements are higher, then put a layer of sound-absorbing cotton on the soundproofing panels, then the effect will be better, I hope my answer can help you.
