Nonlinear damping[edit]Nonlinear passive damping offers important advantages compared to purely linear designs.[9] Nonlinear damping using an odd function, for example cubic damping, allows the user to damp the resonance without increasing the energy in the frequency response tails and hence overcomes several limitations of a purely linear design.
