Background
Modern cars have shock absorbers in their suspensions and trucks typically have shock absorbers mounted only on the front axle. When the automobile runs on an uneven road, the automobile body can vibrate, the vibration of the automobile body can be quickly attenuated by the vibration absorber, and the energy of the vibration is consumed by the resistance of the self oil flow. When the frame and the axle move relatively, oil in the shock absorber flows from one chamber to the other chamber repeatedly through narrow holes, slits and other passages, and the friction between the hole wall and the oil and the friction between molecules in the oil form resistance to the vibration of the vehicle body. The damping force converts vibration energy of the vehicle body into heat energy, and the heat energy is absorbed by the oil and the shell.
