用数值方法研究了外谐波激励对非线性摆链本征模态的影响。我们特别展示了当耦合摆同时受到外部和参数激励时，孤子的存在和稳定域是如何被改变的。这种稳定机制为控制阻尼非线性周期晶格中的能量局域化现象开辟了道路，从而实现有效的能量输运应用。(C) 2016 Elsevier B.V.版权所有
The influence of an external harmonic excitation on the intrinsic localized modes of a chain of nonlinear pendulums is numerically investigated. We show, in particular, how the existence and stability domains of solitons are modified when the coupled pendulums are simultaneously subjected to external and parametric excitations. This stabilization mechanism opens the way towards the control of the energy localization phenomena in damped nonlinear periodic lattices for efficient energy transport applications.
