Data-processing
基于FFT的功率谱分析程序设计与应用
2)对实验所采集的转子振动信号进行频谱分析
2.讨论:
1) 信号经过均值化处理或不经过均值化处理的结果比较
2)采用不同窗函数时的谱结果(矩形窗函数, 汉宁窗函数,汉明窗)
3)典型函数的频谱(矩形窗函数, 汉宁窗函数,直线,阶跃函数,δ函数,方波,三角波等)
4)整周期和非整周期采样时两者的比较
5)讨论实验结果
(Based on the FFT power spectrum analysis of program design and Application2) on experimental collection of the rotor vibration signal spectrum analysis2 discussion:1) the signal through the mean treatment or not after a mean treatment results comparison2) using different window function spectral results ( rectangle window, Hanning window function, the Hamming window )3) the typical functions of spectrum ( rectangle window, Hanning window function, linear, step function, function, square wave, triangular wave)4) the whole cycle and non-integer-period sampling time comparison5) discussion of experimental results)
