<P>PROBLEM TO BE SOLVED: To simply and accurately calibrate the crosstalk correction coefficient of a multiple component force detector provided in a rolling resistance testing machine. <P>SOLUTION: An inventive calibration method for multiple component force detector is used for a multiple component force detector provided in a rolling resistance testing machine 1 including: a spindle shaft 5 to which a tire T is mounted; a traveling drum 3 having a simulation traveling road surface 2 against which the tire T is pressed; and a rotational torque meter 7 provided on a revolving shaft of the traveling drum 3. In this method, when processing for calculation of a force acting on the tire T from a measured value of the multiple component force detector is performed by using a crosstalk correction coefficient which corrects effect of a crosstalk occurring in the multiple component force detector, the crosstalk correction coefficient is calibrated by using "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 |
