Parametric excitation of a linear oscillator

The phenomenon of parametric resonance is explained and investigated both analytically and with the help of a computer simulation. Parametric excitation is studied for the example of the rotary oscillations of a simple linear system— mechanical torsion spring pendulum excited by periodic variations of its moment of inertia. Conditions and characteristics of parametric resonance and regeneration...

Dynamics of an oscillator with delay parametric excitation

This paper involves the dynamics of a delay limit cycle oscillator being driven by a time-varying perturbation in the delay: _ x 1⁄4 x t TðtÞ ð Þ εx3 with delay TðtÞ 1⁄4 2þεkþε cos ωt. This delay is chosen to periodically cross the stability boundary for the x1⁄40 equilibrium in the constant-delay system. For most of parameter space, the system is non-resonant, leading to quasiperiodic behavior...

Study on van der Pol Oscillator under Noisy Parametric Excitation

We calculated Eq. (4) by using the Runge-Kutta method. The attractors obtained by the simulations are shown in Fig. 3(a). We can confirm the generation of periodic and chaotic attractors. In order to investigate the attractors in van der Pol oscillator under noisy parametric excitation in detail, we consider the Poincaré map. The result of the Poincaré map are shown in Fig. 3(b). We can see tha...

Suppressing Flow-induced Vibrations by Parametric Excitation

The possibility of suppressing self-excited vibrations of mechanical systems using parametric excitation is discussed. We consider a two-mass system of which the main mass is excited by a ow-induced, self excited force. A single mass which acts as a dynamic absorber is attached to the main mass and, by varying the stiiness between the main mass and the absorber mass, represents a parametric exc...

Studying piezoelastic and piezomagnetoelastic configurations for different excitation frequencies in MEMS energy harvesters

Typically two configurations are used for energy harvesting with different advantages: piezoelastic and piezomagnetoelastic. Best performance of the piezoelastic configuration is when the excitation frequency is close to the resonance frequency. If the input frequency slightly deviates from the natural frequency, the generated power is severely decreased. To tackle the problem, the piezomagneto...
