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 ). See more Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. … See more A damped sine wave or damped sinusoid is a sinusoidal function whose amplitude approaches zero as time increases. It corresponds to the … See more Using the natural frequency of a harmonic oscillator $${\textstyle \omega _{n}={\sqrt {{k}/{m}}}}$$ and the definition of the damping ratio above, we can rewrite this as: See more The Q factor, damping ratio ζ, and exponential decay rate α are related such that When a second … See more Depending on the amount of damping present, a system exhibits different oscillatory behaviors and speeds. • Where … See more The damping ratio is a parameter, usually denoted by ζ (Greek letter zeta), that characterizes the frequency response of a second-order ordinary differential equation. It is particularly important in the study of control theory.
