What does resonance mean in a car?

Hello, when the car reaches a certain speed, the vibration is large, and it is okay to pass this speed. The natural vibration frequencies of each component are superimposed together to cause resonance, I hope it is the best, thank you.

Hello, every car has a resonance point, and the speed of the car at the resonance varies. It is generally believed that the higher the speed of the vehicle at resonance, the better the quality of the car. Resonance occurs around Poussin 100, and resonance occurs at 200.

When you turn on the air conditioner and feel the car shaking, it's not resonance, it's a lack of engine power.

The body is mostly made of metal parts. Large areas of metal parts, at different driving speeds, will produce speed resonance. The resonance of the chassis, door panels, front and rear fenders and other positions will evolve into high and low frequency noise, which affects the driving comfort.

The construction of our shop specializes in dealing with abnormal noise, resonance and silent construction of vehicles to improve the comfort of the whole vehicle.

Resonance is something that every car has, and when it reaches a certain speed, you can feel a lot of noise and vibration, and if you handle it well, you can eliminate it.

Resonance is a term used in physics with a very high frequency, which refers to the situation in which a physical system vibrates with a greater amplitude than other frequencies at a specific frequency; These specific frequencies are called resonant frequencies.

At resonant frequencies, small periodic vibrations can produce large vibrations because the system stores kinetic energy. When the resistance is small, the early resonance frequency is approximately equal to the natural frequency of the system, or the natural frequency, which is the frequency at which it oscillates freely.

The reasons for the resonance of automobiles: 1. The vibration frequency of the engine is equal to the natural frequency of the car. The frequency of vibration of the engine is only related to the speed, so the problem is not with the engine; 2. The design of the car body itself is in line with the staggered natural frequency of the car and the engine frequency, but due to the use and wear of the car and other reasons, the natural frequency of the car changes, resulting in the resonance of the car at a new speed; 3. The resonance you said about driving to more than 80 miles does not exist scientifically, because the resonance frequency must be quite a natural frequency to resonate, therefore, it is only possible to resonate at a speed equal to about 80 miles, that is to say, when your speed is farther away from 80 miles, the weaker the vibration of the car, that is, either lower than 80 miles or higher than 80 miles, the resonance will only appear in the position where the speed is very close to more than 80 miles; 4. However, because the resonance is a great safety threat (it can be strong enough to crack the car), please do not reduce the resonance by driving at a speed of more than 80 miles!

Either you only drive a slow car below 80 mph, or you can only go to the garage to check and adjust the whole body.
