<P>PROBLEM TO BE SOLVED: To provide a calibration method by which a crosstalk correction coefficient of a multiple component force detector installed on a rolling resistance testing device is calibrated conveniently and highly accurately. <P>SOLUTION: A calibration method of a multiple component force detector installed on a rolling resistance testing device 1 comprises a spindle shaft 5 having a tire T mounted thereon, a traveling drum 3 having a simulated traveling road surface 2 onto which the tire T is pressed, and a rotational torque meter 7 provided on a rotation shaft of the traveling drum 3. When a process of calculating a force applied to the tire T from the measurement value of the multiple component force detector is conducted using a crosstalk correction coefficient that corrects the influence of a crosstalk generated in the multiple component force detector, the crosstalk correction coefficient is calibrated by means of "rolling test data" consisting of a rotational torque measured by the rotational torque meter 7 and a force measured by the multiple component force detector. <P>COPYRIGHT: (C)2012,JPO&INPIT |
