| 81 | TIRE ROLLING-RESISTANCE TESTING METHOD AND TESTING DEVICE | EP14879432.4 | 2014-10-30 | EP3093642B1 | 2018-12-12 | MIYAZAWA Ken |
| This invention improves the precision and reliability with which rolling resistance can be measured. This rolling-resistance testing method includes a rolling-resistance measurement stage and a determination stage. In the rolling-resistance measurement stage, a component force meter is used to measure the tangential axial force that occurs in a tire axle when the tire is rotated under load. In the determination stage, the axial force is measured in a no-load stopped state in which the tire has been separated from a drum, said axial force is compared to a threshold, and if the axial force is greater than said threshold, a determination that an anomaly has occurred in the test is made. | ||||||

| A time-series waveform of tire vibration detected by an acceleration sensor is windowed by a windowing means, time-series waveforms of the tire vibration are extracted for respective time windows, and feature vectors of the respective time windows are calculated. Then kernel functions are calculated from the feature vectors of the respective time windows and road surface feature vectors, which are the feature vectors for the respective time windows calculated from the time-series waveform of the tire vibration obtained for distinctive road surface conditions calculated in advance. And the road surface condition is determined by comparing values of discriminant functions using the kernel functions. As a result, the road surface condition can be determined from the time-series waveform of the tire vibration without detecting peak positions or measuring the wheel speed. Moreover, robustness against changes in tire size can be added to the determination of the road surface condition. | ||||||

| A system and method for selectively removing tire material from the bead portions of a cured tire to reduce one or more harmonics of at least one uniformity parameter are disclosed. According to aspects of the present disclosure, tire material is selectively removed using a plurality of direct address commands. The direct address commands specify ablation parameters for discrete ablation segments at specific angular locations around the bead of the tire. The direct address commands are generated by analyzing the desired ablation pattern for the bead of the tire. The ablation device can then be controlled to selectively remove tire material in discrete ablation segments at identified addresses pursuant to the direct address commands to achieve the desired ablation pattern on one or more tracks along the bead portion of the tire using a single pass of the ablation device. | ||||||

| A pressure gauge of which the presence or absence of a measurement error can be easily checked is provided. A pressure gauge includes: a piston; a first conversion mechanism converting a linear motion of the piston against an elastic force of a spring into a rotating motion about a first rotation shaft, the linear motion being caused by the pressure transmitted from a target to be measured; an index that is fixed to one end side of the first rotation shaft; a dial; momentum detecting means for detecting momentum indicating an amount of movement of the piston; and a pressure sensor measuring a pressure value of the pressure acting on the internal space of the cylinder. Determining means determines whether a difference between a first measurement value and a second measurement value exceeds a predetermined value, the first measurement value being estimated from the momentum detected by the momentum detecting means, the second measurement value being measured by the pressure sensor. Notifying means notifies a user if the difference between the first measurement value and the second measurement value exceeds the predetermined value. | ||||||
