摘要
阐述了频谱分析方法 ,并采用快速富里叶变换 (FFT)算法对Y38A滚齿机的传动误差进行了频谱分析 ,得出了传动误差的富里叶频谱 ,结果表明 。
The methods of spectrum analysis are discussed.The transmission error of the gear hobbing machine Y38A has been analysed by means of the FFT algorithm and its Fourier spectrum has been obtained.The analysis result indicates,that the Fourier spectrum is in keeping with the running frequency of the transmission elements.
