Abstract: Disclosed is a multi-component force measurement spindle unit that accurately measures forces and moments applied to a tire in a tire testing machine. The multi-component force measurement spindle unit of a tire testing machine includes: a spindle shaft on which a tire can be mounted; an inner sleeve that rotatably supports the spindle shaft via a bearing part; an outer sleeve arranged on an outside of the inner sleeve along an axial center direction of the spindle shaft; a multi-component force measurement sensor that connects an end of the inner sleeve and an end of the outer sleeve to each other and is capable of measuring a load acting on the outer sleeve from the inner sleeve; and a cooling part that cools the inner sleeve.

Abstract: 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.
