介绍了谐波分析法的原理,阐述了谐波分析法在汽车轮毂跳动量检测及分类判定中的应用。通过傅里叶变换,计算出了谐波的幅值和初始相位,使相位按照特定的步长从0o变化到360o,画出了谐波波形。通过傅里叶变换将离散的数据分解成周期性的谐波数据,增强了采用谐波分析法检测轮毂质量的直观性。
介紹瞭諧波分析法的原理,闡述瞭諧波分析法在汽車輪轂跳動量檢測及分類判定中的應用。通過傅裏葉變換,計算齣瞭諧波的幅值和初始相位,使相位按照特定的步長從0o變化到360o,畫齣瞭諧波波形。通過傅裏葉變換將離散的數據分解成週期性的諧波數據,增彊瞭採用諧波分析法檢測輪轂質量的直觀性。

The principles of harmonic analysis were introduced,the harmonic analysis was expoun-ded in the application of automobile wheel hub quantity detection and classification decision.With the Fourier transform,calculating the harmonic amplitude and initial phase,and phase changed according to the particular step from 0oto 360o,the harmonic wave can be drew.With the Fourier transform,the discrete data were decomposed into periodic harmonic data,and it enhances the harmonic analysis tes-ting hub quality intuitiveness.
