论文摘要
我们从实验和理论上研究了超严格驱动的膜谐振器中持续反应的现象。该术语表示在极端频率范围内的振动状态的发展。我们通过使用先进的光学干涉法直接对振动状态进行成像，揭示了持续响应状态的潜在机制。我们认为持续状态与驱动模式的高阶弯曲模式和高阶泛音之间的非线性相互作用有关。最后，我们为膜可以采用的不同振动状态提出了一个稳定图。
We study experimentally and theoretically the phenomenon of persistent response in ultra-strongly driven membrane resonators. This term denotes the development of a vibrating state with nearly constant amplitude over an extreme wide frequency range. We reveal the underlying mechanism of the persistent response state by directly imaging the vibrational state using advanced optical interferometry. We argue that the persistent state is related to the nonlinear interaction between higher order flexural modes and higher-order overtones of the driven mode. Finally, we propose a stability diagram for the different vibrational states that the membrane can adopt.
