文摘

Nonlinear lumped parameter model of electrodynamic shaker is proposed.

New nonlinear viscoelastic model is proposed for accurate low frequency response.

Model parameters estimated through non-destructive methods.

Model is able to predict fundamental and harmonic components of shaker's response.

Model is able to predict DC offset in displacement response.
