To simply and highly precisely 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 of the invention is a method of calibrating a multi-component force detector provided in a rolling resistance testing machine (1) including a spindle shaft (5) attached with a tire (T), a running drum (3) with a simulated road surface (2) for pressing the tire (T) thereon, and a rotation torque meter (7) provided in a rotation shaft of the running drum (3), wherein when performing a process of calculating a force acting on the tire (T) 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 (7) and a force measured by the multi-component force detector. |
