Damping ratio of a vibrating system

(Mechanical vibrations – V.P. SINGH)

The equilibrium in the vibrating system is maintained by arresting the motion of the body by using a spring and damper.

Damping ratio is defined as the ratio of the damping coefficient (C) to the critical damping coefficient (Cc). Depending on the damping coefficient, a system can be categorized as under damped system (zeta <1), critically damped (zeta = 1), over damped system (zeta >1).
