High Speed Unifomity Tester


OVERVIEW

Low speed uniformity testers are only capable of measuring RFV and LFV at rotational speeds around 60rpm (60 rpm on a 29rpm outside diameter tire = 5 mph). Some other conditions, such as Plysteer and Conicity are derived from these measurements. Testing force variation at low speeds is similar to testing for static unbalance only.

In the high speed uniformity mainly the RFV and the Tangential Force Variation which has not been addressed yet play the important role. The increase of the LFV is in most cases neglectable! The influence of TFV begins to develop at about 60 kmph and the full influence is felt at about 120 kmph. The known influences of TFV on any vehicle are a quickly evolving and ever increasingly interesting topic. TS is one of the leading suppliers of the high speed uniformity machines. The HSU of TS combine innovative approaches like damping concrete for high normal frequencies of the machine frame with established components like the Kistler measurement hub to generate best test results.
