The design of the car shock absorber.

From the history of the creation of shock absorbers. Shock absorbers have long been used in the automotive industry. The first samples were far from modern representatives. Before the appearance of separate shock absorbers and springs, springs were used, performing the functions of both the first and second. But in connection with the development and introduction of an independent suspension, there was a need to separate them. At first, cylindrical springs were invented, and then cylindrical shock absorbers. It was a big jerk forward in the automotive industry. Firstly, the maintainability of the spring suspension is much easier than the springs, and secondly, it is less susceptible to wear, and it is easier to configure. There was another pleasant moment — the suspension now did not creak like on a cart. If you look at the details that are between the driver and the road, you can see that these are a variety of springs, rubber gaskets, seat, tires, shock absorbers. Each of these details has its own resonant frequency, which increases the comfort of driving. Car suspensions are built in such a way that it would be comfortable to move. How to achieve this? In order to answer this question, you need to understand that the car always experiences the suspension fluctuations, but you need to know, which frequency fluctuations are comfortable for people. The fact is that by nature a person moves on two legs, and therefore, the usual frequency of oscillations of about 2 Hz. If the car suspension makes fluctuations with a greater frequency, then a person shakes in it. If less, then the effect of marine disease arises, a person rinses. To avoid this to avoid, designers calculate the resonant frequency of the suspension fluctuations. They select the spring -based spring for each car, which depends on the mass of the car.
