Notes:
In current tire durability tests, technicians must stop tests periodically to inspect eachtire, resulting in a time consuming, expensive, and relatively subjective process. Online tiremonitoring would thus be a dramatic improvement over the current methodology. If such a systemcould be extended to on-line vehicle use, it could dramatically increase safety, reduce downtime,and lead to better fuel efficiency in commercial and passenger cars and trucks. A near real-timesystem to monitor the initiation of bead area damage in rolling tires was developed using vibrationdata collected from the wheel end spindle. To generate an accurate model of the forced response ofthe wheel end spindle, a tire on a fixed spindle was impacted with a modal punch while the tire waspreloaded against a plate. The frequency response functions acquired from this system were thenused to develop a rotating tire model consisting of time-delayed forcing functions applied to the tirepatch at the rolling frequency; this model was used to assist in interpreting the results from the nearreal-time monitoring system. The near real-time continuous monitoring system has been deployedin a manufacturing test environment and utilizes frequency data from three mutually orthogonalacceleration measurements. These data are combined to create a highly sensitive composite indexthat identifies when the initiation of bead area damage has occurred
