强迫弦振动的不规则波长驻波与混沌

Anomalous Wavelength Standing Waves and Chaos of Forced Vibration Strings

摘要: 介绍强迫弦振动的不规则波长驻波与实验观测结果.对于一端固定,另一端受到简谐驱动的弹性弦,可以产生不规则波长的驻波振动,从而会发生波长不等于整数倍的二个驻波振动的"争夺"振动,出现混乱振动.给出了混沌振动轨迹的实验测量方法和结果.

Abstract: Results that forced vibration strings can produce the standing waves of anomalous wavelength is presented.The superposition of both the anomalous wavelength standing wave and normal wavelength standing wave may produce chaos vibrations.The chaotic vibration tracks are given by experiments
