论文摘要
我们报告了两个对称弱耦合非线性振荡器的系统中的非线性振动定位。具有分段线性刚度的两个自由度模型显示出与局部溶液的分叉。一项实验研究采用了两条弱耦合的光束，触摸塞子的较大振动幅度，证实了非线性定位。
We report nonlinear vibration localisation in a system of two symmetric weakly coupled nonlinear oscillators. A two degree-of-freedom model with piecewise linear stiffness shows bifurcations to localised solutions. An experimental investigation employing two weakly coupled beams touching against stoppers for large vibration amplitudes confirms the nonlinear localisation.
