最近南京航空学院振动工程研究所新研制出MFD-1机械故障分析软件包。该软件包能分析双通道数据。它不仅能对一般的功率谱、频谱、细化、倒谱、自相关等进行分析,而且可以分析频响函数、相干函数、互谱、互相关。还可以分析三维谱图、轴轨迹、概率密度等。此外,还能对振动数据进行幅度解调和频率解调。 Nanjing Institute of Aeronautical Engineering recently developed a new MFD-1 mechanical failure analysis software package. The package analyzes dual channel data. It not only can analyze general power spectrum, spectrum, refinement, cepstrum, autocorrelation and so on, but also can analyze frequency response function, coherence function, cross spectrum and cross-correlation. You can also analyze three-dimensional spectra, axis traces, probability density, and more. In addition, the vibration data can be amplitude demodulated and frequency demodulated.
