研究了两个振动微机械悬臂梁之间的动力学相互作用。在实验中，高频悬臂的尖端位于第二低频悬臂的表面附近。由于两个表面之间的高度非线性相互作用力，低频悬臂梁的热振荡调制高频悬臂梁的驱动振荡。的耗散和频率的两个杠杆被示出耦合，并提出了一个简单的模型的相互作用。这里研究的相互作用可能是有用的未来的微和纳米机电系统的机械信号处理的设计，他们也可以帮助实现耦合的非线性动力学实验的机械模式。(C)2013 AIP Publishing LLC.
Dynamic interactions between two oscillating micromechanical cantilevers are studied. In the experiment, the tip of a high-frequency cantilever is positioned near the surface of a second low-frequency cantilever. Due to the highly nonlinear interaction forces between the two surfaces, thermal oscillations of the low-frequency cantilever modulate the driven oscillations of the high-frequency cantilever. The dissipations and the frequencies of the two cantilevers are shown to be coupled, and a simple model for the interactions is presented. The interactions studied here may be useful for the design of future micro and nanoelectromechanical systems for mechanical signal processing; they may also help realize coupled mechanical modes for experiments in non-linear dynamics.
