Abstract
A method for characterizing spindle forces of a tire uniformity machine includes receiving a tire in an apparatus having an upper spindle and rim and a lower spindle and rim, wherein the rims capture the tire therebetween. A measurement data waveform is collected and an angular offset between the rims to define an engagement position is determined. The measurement data waveform is designated as a tire result waveform, and the measurement data waveform is appended to a collection of measurement data waveforms for each engagement position. Once the predetermined number of waveforms for the engagement position has been obtained, an average waveform for each engagement position is computed. A characterization waveform for each average waveform is then generated.
