CALIBRATION METHOD FOR MULTI-COMPONENT FORCE DETECTOR PROVIDED IN ROLLING RESISTANCE TESTING MACHINE

摘要

The calibration method for a multi-component force detector is a calibration method for a multi-component force detector provided in a rolling resistance testing machine comprising a spindle to which a tire is mounted, and a traveling drum having a simulated traveling road surface against which the tire is pressed, wherein when processing for calculating force acting on the tire from the measurement value of the multi-component force detector using a crosstalk correction factor for correcting the influence of crosstalk occurring in the multi-component force detector is performed, a test is conducted using at least one or more reference tire the rolling resistance value of which is already known, and the crosstalk correction factor is calibrated using “rolling test data” composed of force measured by the multi-component force detector during the test using the reference tire, and the rolling resistance value of the reference tire used for the measurement.

1. A calibration method for a multi-component force detector provided for a rolling resistance testing machine that has a spindle on which a tire is mounted and a traveling drum with a simulated traveling road surface against which the tire is pressed, the calibration method comprising:
performing a test using at least one reference tire whose rolling resistance value is known to thereby obtain rolling test data made up of a force measured by the multi-component force detector during the test using the reference tire; and calibrating a crosstalk correction coefficient for correcting an influence of crosstalk occurring at the multi-component force detector using the rolling test data and the rolling resistance value of the reference tire.
