To overcome the limitations of current causality techniques and make full use of harmonic oscillation characteristic of experimental data, we consider a harmonic oscillator, or a set of harmonic oscillators, to represent the environmental inputs.
Steady state harmonic oscillation has been studied almost exclusively.
Chapter 8 investigates the sensitivity analysis of displacement amplitude for structures under forced harmonic oscillation.
For harmonic oscillation the differential equations are solved in closed analytical form.
For harmonic oscillation the differential equation is solved for bending displacement by applying the Frobenius method of series solution.
Forced harmonic oscillation of a system involving a piezoelectric actuator coupled via Hertzian contact to an elastic beam is modeled.
Given the nonlinear and viscoelastic nature of the material, its dynamic response could be complicated and deviate from the desired harmonic oscillation pattern.
The resonance curves also show that a super-summed-and-differential harmonic oscillation can occur at the tuning frequency when the magnitude of excitation is comparatively large.
Well-known multimass models of vocal folds are useful to describe main behavior observed in human voicing but their principle of functioning, based on harmonic oscillation, may appear complex.
Quiescent H-modes (QH-modes) are a candidate regime for ITER and future reactors because they maintain a stationary pedestal without ELMs via additional edge transport generated by either an edge harmonic oscillation, broadband turbulence, a limit cycle oscillation, or some combination thereof.
Our solution is correct through the second-order terms in a smallness parameter, which we identify with the amplitude of the harmonic oscillation at the boundary, and it complements the first-order solution presented in an earlier work.
