Damping ratio zeta
WebThe damping ratio symbol is zeta (ζ), that can change from undamped like ζ = 0, underdamped like ζ < 1, critically damped like ζ = 1 & overdamped like ζ > 1. The performance of oscillating systems is frequently used a different engineering fields like control, chemical, mechanical, structural & electrical. WebThe damping ratio is a parameter, usually denoted by ζ (zeta), [1] that characterizes the frequency response of a second order ordinary differential equation. It is particularly important in the study of control theory. It is also important in the harmonic oscillator . The damping ratio provides a mathematical means of expressing the level of ...
