We demonstrate the emission of solitons from a resonantly excited localized standing wave in a nonlinear chain of spring-coupled masses. The localized wave in this system is induced by a properly designed “impurity” and vibrates around the “impurity” with an intrinsic frequency. We observe that, when subjected to an external forcing, it is amplified to a large amplitude under the nonlinear resonance, and, then, its wave envelope splits apart leading to the release of most of its energy in the form of a large-amplitude traveling soliton. The experiment also shows that the rate of the emission can be controlled by finely tuning the driving parameters, thereby providing a feasible and controllable way for creation of solitons.

共振局域波发射孤子的实验证明

我们证明了弹簧耦合质量的非线性链中共振激发的局部驻波的孤子发射。该系统中的局部波由适当设计的“杂质”引起,并以固有频率在“杂质”周围振动。我们观察到,当受到外力作用时,它在非线性共振下被放大到一个很大的幅度,然后,它的波包分开,导致大部分能量以大幅度传播的形式释放出来。孤子。实验还表明,可以通过微调驱动参数来控制发射速率,从而为创建孤子提供了一种可行且可控的方式。
