摘要
利用微机的声卡、Matlab/Simulink,以及耳麦作为声音采集设备,通过快速傅里叶变换分析,提出一种基于声卡的测量刚体固有频率的方法.以音叉固有频率测量实验为例,验证系统的可行性,表明该测量系统结构简单,易于实现.
With PC＇s sound card, Matlab/Simulink, microphone used as sound collecting device, by means of FFT（fast fourier transform）, a way to admeasurement of rigid body＇s natural frequency based on matlab/simulink is presented. Taking tuning fork natural frequency measurement experiment for example, it finds that the new method is feasible, and the measurement system is simple and easy to implement.
