Abstract
A method for analyzing the vibration of a tire uniformity machine having a number of rotating components uses the signals from load cells when the machine idle to output voltage signals that are then amplified and input into a computer as unfiltered, amplified voltage signals. The signals are converted into a power spectrum and selected groups of frequencies and their amplitude are compared with acceptable amplitudes for the frequencies generated by various rotating parts of the machine. When at least one of the amplitudes for different frequencies is greater than at least one of the acceptable amplitudes for the frequencies generating different rotating parts of the machine, the computer outputs an alarm signal.
