文章以音叉弦线非线性振动为基础,通过音叉弦线长度、张力的调节,观察和研究振动由混沌向周期有序,或周期有序向混沌的运动变化过程;结合虚拟仪器LabVIEW软件平台,对原始信号采集数据序列,然后由LabVIEW进行信号处理,实时观察到混沌运动相图,并对理论计算相图和实际采集信号的相图进行比较,为混沌现象的研究提供一种新的实验方法.

A new way of studying chaos motion is given in the nonlinear vibration system based on the tuning fork.The motion changes from chaotic to periodic and its reversion can be seen by regulating the length and tension of a suspension wire which links the tuning fork.Furthermore,a new data collection and signal processing program is written by LabVIEW language to display the real-time and theoretic phase diagrams of the chaos motion on the computer.Thus,a new experimental method for studying chaos motion is presented.
