摘要
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0°变化到360°,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。
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.
