Sensor calibration device and method for a tire

摘要

A sensor calibration device and method of construction for a force variation machine includes a circular plate having a test measurement region defined thereon. The test measurement region has a circumferentially extending inner track and a circumferentially extending outer track, the outer track having a projection and a valley for sidewall bulge and valley simultion formed therein and the inner track having a first and a second step formed therein separating the inner track into outward and inward inner track portions. A circumferentially extending radial edge track is provided having a first and a second step formed therein separating the edge track into outward and inward edge track portions. The projection and valley on the outer track have a depth equivalent to tire sidewall bulge and valley limits, respectively. The first and second steps in the inner track have a depth equivalent to a tire lateral run-out limit. The first and second steps in the edge track have a depth equivalent to a radial run-out limit.
