Shock absorber is a relatively simple type among all shock absorber types, and its main material is a small amount of metal or other materials. But don't underestimate this small element. Its effect is no less than that of other shock absorbers. It is generally used on some vehicles. Shock absorber is also a kind of vibration damping and isolation element commonly used in engineering.
According to the force, the shock absorber can be divided into compression type, shear type, compression shear composite type, etc. The biggest advantage of the shock absorber is that it has large damping, good damping effect near the resonance frequency, and is suitable for vibration isolation in vertical, horizontal, and rotational directions. The stiffness has a wide range of options. Compared with steel ball valve, its disadvantage is that its vibration isolation performance is easily affected by temperature, and its performance is poor when used at low temperature. The static compression is low and the natural frequency is higher than 5Hz, so this kind of shock absorber is not suitable for equipment with low interference frequency (natural frequency lower than 5Hz) and heavy weight.
Many people do not expect that the engine will have something to do with the shock absorber. In fact, just remember that where there is vibration, there can be a shock absorber. This shock absorber may be a shock absorber, a ball valve shock absorber, or even other types of shock absorbers. It is obvious that they exist to reduce vibration and noise, which can kill two birds with one stone. Then why should the engine use a shock absorber? It is very simple. Just as we said, where there is vibration, there is a shock absorber. After the engine starts, there will be high frequency vibration and loud sound. At this time, it is necessary to use a shock absorber to reduce the vibration sense and noise. In fact, this is to make people who are operating the engine more comfortable, and also to protect the engine from vibration, which will reduce its life. Take a car for example. If the engine of the car does not have a shock absorber, you will feel very bumpy when driving on a flat road. And the noise is also very loud. This is the advantage of the shock absorber.
