A model is presented based on the Duffing equation, which describes the behavior of the nanomechanical resonators.纳机械谐振器有几百兆甚至更高的工作频率,本文利用达芬方程作为纳机械谐振器的动力学方程,用数值方法求解了电磁驱动纳机械谐振器的动态特性,计算表明谐振器有明显的非线性特性,与国外已有的实验结果相符合,该分析方法可以为纳机械混频器设计提供参考。
An advantage of Galerkin method was that, for a given trial function, the residuals of the dynamic von Karman partial differential equations could be eliminated easily, thereby the governing equation of an annular thin plate for forced vibration, namely the hard-spring type of Duffing equation, could be obtained.为研究环形薄圆板非线性振动特性,用伽辽金法消除动态卡门偏微分方程的残值,推导出了环形薄圆板的受迫振动控制方程,即硬弹簧型达芬方程;用KBM法求解达芬方程,定性地探讨了边界条件、阻尼比、外激振力和内外半径比对环形薄圆板振动的影响,得到了4种边界条件下共振时激起的振幅均随半径比或阻尼比的增大而减少的结论;取外激振力作为控制参数,进行理论分析和数值仿真,发现随着外激振力的增大,动力系统从围绕1个焦点的周期运动转变成围绕2个焦点的周期运动。
