耦合非线性振子非线性简正模的存在性

Existence of nonlinear normal modes for coupled nonlinear oscillators

Dirk Hennig

摘要:

本文证明了一般两个耦合非线性振子系统非线性正规模的存在性。促进常微分方程的比较原理,它表明,存在着代表振动的系统一致的精确解。相关联的空间局部化的时间周期性的解决方案功能的振荡器的异相和同相运动。

英文摘要:

We prove the existence of nonlinear normal modes for general systems of two coupled nonlinear oscillators. Facilitating the comparison principle for ordinary differential equations it is shown that there exist exact solutions representing a vibration in unison of the system. The associated spatially localised time-periodic solutions feature out-of-phase and in-phase motion of the oscillators.
