WebSep 3, 2024 · The free vibration of a string can be modelled with the partial differential equation: T ∂ 2 y ( x, t) ∂ x 2 − ρ ∂ 2 y ( x, t) ∂ t 2 = 0. Where T is the axial tension on the string, ρ is the mass density, y is your transverse displacement, and x is the position along the string length. The solution of this equation can be obtained ...

Damping - Wikipedia
WebJun 15, 2024 · Damping of the mooring system affects the surge and sway motions of the floating structures, such as FPSO and WEC ( Huse, 1986; Weller et al., 2014 ). The main … 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. Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, … See more Depending on the amount of damping present, a system exhibits different oscillatory behaviors and speeds. • Where the spring–mass system is completely lossless, the mass would oscillate indefinitely, … 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. It is also important in the harmonic oscillator. … See more The Q factor, damping ratio ζ, and exponential decay rate α are related such that See more Viscous Drag When an object is falling through the air, the only force opposing its freefall is air resistance. An object falling through water or oil would slow down at a greater rate, until eventually reaching a steady-state velocity as the drag … See more A damped sine wave or damped sinusoid is a sinusoidal function whose amplitude approaches zero as time increases. It corresponds to the underdamped case of damped second … See more Using the natural frequency of a harmonic oscillator $${\textstyle \omega _{n}={\sqrt {{k}/{m}}}}$$ and the definition of the damping ratio … See more In control theory, overshoot refers to an output exceeding its final, steady-state value.
