摘要: 针对一种产生机械孤波的多摆耦合系统建立了动力学模型,利用MATLAB进行了数值模拟并搭建装置进行了实验.模拟显示系统存在多种形式的孤波解.在实验中也发现了机械孤波,而且实测孤波速度与驱动强度的依赖关系定性上与数值模拟结果一致.

Abstract: A mechanical system that possess solitary wave is studied. We model the dulums, in which the dynamic equation can be derived accordingly. Then we carry out system as N coupled pennumerical simulation with MATLAB. The simulation shows that the system permits three types of solitary wave solution. Moreover, the calculated velocity of solitary wave is in agreement well with the experimental measurement, which verifies the validity of our model.

Key words: mechanicalsolitary wave, numerical simulation, differential method, MATLAB
