摘要
为了简单直观地呈现混沌现象,研制了受周期驱动力驱动的混沌摆实验系统.实验系统由力学机构、采集机构和数据处理分析仪组成.力学机构是受周期外力驱动的复摆;采集机构采用无触点角度传感器,通过串口通信实时将数据传输给计算机;数据处理分析仪用虚拟仪器平台LabVIEW软件编程实现.该系统可实时显示反映混沌基本特征的角度时序图、角速度时序图和相图.
In order to intuitionisticly show phenomena of chaos, an experiment system of chaotic pendulum driven by periodic external force is designed. There are three parts, namely mechanical section, acquirement section and analyzer, in the system. The mechanical section is a pendulum driven by periodic external force; data are acquired by breakerless angle sensor and transferred to computer through serial communication; the analyzer is a virtual instrument written by LabVIEW. The angletime curve, angular velocity-time curve and phase curve can be displayed in real time.
