ζ = 1/ 2Q = α / ωn Where Q factor is also a non-dimensional measure of the damping of the system. If the value of Q is high, then the system exhibits slow damping corresponding to the oscillation. 'α' represents the decay rate parameter.

How is damping ratio measured?
Based on the magnitude-frequency characteristic, the half band power method is used to measure the damping ratio. In order to investigate the effects of vibration magnitude on the damping properties, the characteristic of the vibration transfer rate versus excitation magnitude at 210 Hz is measured.
How do you find the damping ratio in an equation of motion?
The damping ratio formula is ζ=c2√(km) ζ = c 2 ( k m ) .
What is damping ratio ζ?
The damping ratio is a measure describing how rapidly the oscillations decay from one bounce to the next. The damping ratio is a system parameter, denoted by ζ (zeta), that can vary from undamped (ζ = 0), underdamped (ζ < 1) through critically damped (ζ = 1) to overdamped (ζ > 1).
How do you calculate damping value?
The critical damping coefficient (cc) is twice the product of the mass (m) and natural frequency (ωn) of the oscillating object: cc = 2mωn. So, find the product of the mass and natural frequency and multiply it by 2 to obtain the critical damping coefficient.
