Abstract
Basic principle for the dynamic balance detection of wheels is analyzed, and a circuit for signals detection is designed. In order to detect the vibration signal with a low SNR, time domain discrete vibration signal is transferred into one of the frequency domain using FFT algorithms after pre-processing the sampling data. According to the dynamic balance velocity detected, the amplitude and phase of the vibration signal relative to the unbalanced magnitude of the wheels were obtained through the amplitude and phase frequency spectrum. Experimental results show that the method is accurate and effective for measuring the unbalanced amplitudes and phases of wheels.
