大型机械设备的正常运行的重要性逐渐被大家所认识,基于FFT频谱分析与频谱图显示的原理对轧钢机的振动信号分析,FFT是计算离散傅里叶变换的一种重要的计算公式,频域分析的编程中以FFT算法为基础,在对时域波形进行采样后,经过FFT处理离散数据,最终得到相关量的频谱图,经过频谱分析后,提出机械零部件出现故障时的信号特征,并成功诊断故障所在。
The importance of the normal operation of large machinery and equipment is gradually recognized by everyone. Based on the principle of FFT spectrum analysis and spectrum display, the vibration signal analysis of the rolling mill is an important calculation formula for calculating the discrete Fourier transform. The frequency The domain analysis programming is based on FFT algorithm. After sampling the time-domain waveform, the discrete data is processed by FFT to obtain the spectrum of the relevant quantity finally. After the spectrum analysis, the signal characteristics of the mechanical components are presented. And successfully diagnosed the fault lies.
