Data Measurement and Analysis Method for YLJ Series Tire Uniformity Testing Machine

This paper provides a concise description of the international development of the low-speed tire uniformity testing machine (TUTM). And particular emphasis is given to the developing history of YLJ series TUTM, researched and developed independently by MESNAC Co., Ltd. It is well known that data measurement and analysis are fundamental to a TUTM. However, very few studies of testing mechanism of tire uniformity have been reported. The primary subject of this paper is to describe operational principle, measurement of force, data measurement and analysis methods of YLJ series TUTM. It also shows the good property of YLJ series TUTM combined with the experimental data of a 215/70R15 97H tire repeated test 10 times.
