The Shock absorber

The shock absorber

In a vehicle the shock absorber is the nexus between sprung mass and unsprung mass (or unsprung weight). Unsprung mass responds to the irregularities of the road. There are fluctuations of frequencies above 12 Hz. The shock absorber absorbs and prevents the total transmission of the sprung mass. It would be virtually impossible to drive without shock absorbers given that the vehicle could not absorb these fluctuations. The mission of the shock absorber is to transform kinetic energy into thermal energy.
