Description

We have developed a instrument for measuring coefficient of friction on wheels, moving on wheel tread with small creepage, which is called "Mobile u-tester." The instrument is constructed with support system and measuring unit, which is driven by flexible rack, pinion and a pulse motor. The measuring unit carries a measuring roller, which is driven by timing belt and pulse motor. Controlling above two motors then it is able to obtain small creepage condition. Meanwhile, coefficient of friction is calculated from normal force, which is supplied by a spring, and friction force measured by load cells. At first, we have measured coefficient of friction on real wheels under non-dismantling condition. Then, we have obtained rough characteristics of creep force. Finally, we have captured the effect of lubricant on coefficient of friction.
