In engineering, the damping ratio is a dimensionless measure describing how oscillations in a system decay after a disturbance. Many systems exhibit oscillatory behavior when they are disturbed from their position of static equilibrium. A mass suspended from a spring, for example, might, if pulled and released, bounce up and down. On each bounce, ...
for a linear time-invariant system of the second order described by the differential equation the damping ratio is the value of the factor ? NOTE 1 - ?o is the characteristic angular frequency of the system. NOTE 2 - is the eigen angular frequency of the system.ratio of the actual damping to the critical damping
ratio of actual damping to critical damping; if the damping ratio is less than one a system is said to be underdamped and if it is greater than one a system is said to be overdamped.
Measure for the damping of wind vanes. It represents the ratio between the consecutive damped deflection amplitudes (for example 3rd amplitu-de to 1st amplitude) in one direction.
