The system exhibits response in the directly excited and indirectly excited modes due to modal interaction.
Under in-plane forced excitation the stretching motion is directly excited while the transverse motion is parametrically excited.
When Ω ≈ 2ω2, the steady state value of the higher mode, which is directly excited, is a constant that is independent of the excitation of amplitude F, whereas the amplitude of the lower mode, which is indirectly excited through internal resonance, grows with the excitation amplitude F. This is another example of saturation.
A vibration-based bistable electromagnetic energy harvester coupled to a directly excited primary system is examined numerically.
A microwave of 2.45-GHz frequency is launched from an L-shaped antenna and selected modes are directly excited.
However, unlike directly excited systems, parametric resonance has a minimum threshold amplitude that must be attained prior to its activation.
