论文摘要

本文重新审视了谐音振荡振荡器的共振行为,并特别注意相互共振及其与振幅共振的关系。为此,使用第一和高阶平均仔细研究了不同的共振家族,即主要的原发性(1:1),超谐波(K:1),亚谐波(1:ν)和Ultra-Subharmonic(K:ν)共振。当计算位移的k-th谐波和谐波强迫之间计算相位滞后时,本研究证明当相位滞后等于π/2(相位正交)或3π/4ν时,相共振发生。

This paper revisits the resonant behavior of a harmonically-forced Duffing oscillator with a specific attention to phase resonance and to its relation with amplitude resonance. To this end, the different families of resonances, namely primary (1:1), superharmonic (k:1), subharmonic (1:ν) and ultra-subharmonic (k:ν) resonances are carefully studied using first and higher-order averaging. When the phase lag is calculated between the k-th harmonic of the displacement and the harmonic forcing, this study evidences that phase resonance occurs when the phase lag is equal to either π/2 (phase quadrature) or 3π/4ν.
