Abstract
This work experimentally investigates the impact of nonlinearity on macromechanical parametric amplification. For a strong cubic stiffness nonlinearity we observe jumps in gain (ratio of steady-state vibration amplitude of the externally and parametrically excited system, to vibration amplitude of the externally excited only system) as function of the phase between the external and parametric excitation. These jumps occur at different phase values dependent on up- and downsweeps. Furthermore, an increasing asymmetric phase-gain relationship was observed for strong nonlinearity.
