本文的目的是基于带参数激励的Mathieu-van der Pol-Duffing能量收集器，探讨几种不同的周期性猝发模式的机理。这些突发模式分别被归类为‘延迟子Hopf/supHopf’突发、‘延迟干草叉/干草叉’突发、‘延迟子Hopf/supHopf’突发、‘延迟子Hopf/supHopf’突发和‘延迟子Hopf/折叠周期’突发。由于当轨迹在不同吸引子之间转移时会产生爆发振荡，这意味着爆发振荡的幅度可能足以克服能量采集器的势垒，因此在能量收集方面具有潜在的应用价值。
The purpose of this paper aims to explore the mechanism of several different periodic bursting patterns based on a Mathieu-van der Pol-Duffing energy harvester with parameter excitation. These bursting patterns are categorized as 'delayed supHopf/supHopf' bursting, 'delayed pitchfork/pitchfork' bursting, 'delayed Hopf-pitchfork/Hopf-pitchfork' bursting, 'delayed subHopf/supHopf' bursting and 'delayed subHopf/fold-cycle' bursting, respectively. Since bursting oscillations can be created when the trajectory transfers between/among different attractors, which means the amplitude of bursting oscillations may be sufficient to overcome the potential barrier of the energy harvester, and thus it would have potential application value in energy harvesting.
