METHOD OF CALIBRATING MULTI COMPONENT FORCE DETECTOR PROVIDED IN ROLLING RESISTANCE TESTING MACHINE

摘要

To calibrate a crosstalk correction coefficient of a multi-component force detector provided in a rolling resistance testing machine. A method of calibrating a multi-component force detector provided in a rolling resistance testing machine includes a spindle shaft attached with a tire, a running drum with a simulated road surface for pressing the tire thereon , and a rotation torque meter provided in a rotation shaft of the running drum, wherein when performing a process of calculating a force acting on the tire from a measurement value of the multi-component force detector using a crosstalk correction coefficient for calibrating an influence of crosstalk occurring in the multi-component force detector, the crosstalk correction coefficient is calibrated by using a rolling test data including a rotation torque measured by the rotation torque meter and a force measured by the multi-component force detector.
