Talk about the working principle of shock absorbers, self-inspection methods, and how to choose shock absorbers?

First of all, let's take a look at the shock absorber, which is an important component in the suspension system of the car, which not only supports the weight of the car body, but also plays a role in cushioning and absorbing road bumps and shocks. Therefore, shock absorbers are a crucial part of the safe driving of vehicles.

To put it simply, the shock absorber is to improve the driving comfort of the car, attenuate the vibration of the frame and the body of the parts, the vehicle in the process of driving, the vibration spring is mainly used to absorb bumps and vibrations caused by uneven road surface. As an elastic element, the spring absorbs and filters the bumpy vibration of the road surface, and also produces its own reciprocating bouncing motion. The main function of the shock absorber is to suppress the repeated bounce of the shock absorbing spring after absorbing various shocks brought by the road surface, so as to accelerate the attenuation of the inherent vibration of the spring and provide better driving smoothness for the vehicle.

In practical applications, shock absorbers and springs in automotive suspension systems are used together, where springs play the role of energy storage. The shock absorber plays the role of vibration damping through the transformation of kinetic energy and thermal energy. The shock absorber, whether it is compression stroke or extension stroke, is consuming vibration energy, this process is commonly known as "vibration damping".

Then, as a vulnerable accessory during the use of the car, the shock absorber works well or badly, which will directly affect the stability of the car and the life of other mechanical parts, so we should make the shock absorber often in good working condition.

In terms of the choice of shock absorbers, my own opinion is that foreign brands in the shock absorber industry have the advantage of rolling grade for the technical leadership of domestic brands. Although the shock absorber seems to be a part, but its integration is very high, concentrated machinery, hydraulics, electronic control, sealing technology, etc., is a comprehensive composite technology, the internal sub-parts are complex, high precision requirements, has a profound impact on the performance of the whole vehicle, to develop well, it is not too easy.

It can be said that it is not easy to develop a shock absorber that not only ensures the performance of the whole vehicle, but also has excellent quality attributes of the shock absorber itself. Because of the slightly more advanced passive and active vibration damping systems, only some world-class enterprises have the ability to mass produce and develop related technologies.
