AXLE MULTI-COMPONENT FORCE MEASURING METHOD

PROBLEM TO BE SOLVED: To provide an axle multi-component force measuring method capable of measuring axle multi-component forces of a vehicle in an actually traveling state even in the case that it is structurally difficult to make the vehicle actually travel with a multi-component force meter mounted. SOLUTION: The axle multi-component force measuring method is provided with a shaking process for mounting a plurality of distortion measuring devices 2 to a vehicle 1, mounting a multi-component force meter 4 on its axle, and shaking it by a shaking device 3; a transfer function model identification process for identifying a transfer function model 6 between the distortion measuring devices and the multi-component force meter on the basis of both data of the distortion measuring devices and data of the multi-component force meter acquired in the shaking process; a vehicle actual traveling process for making the vehicle actually travel with the multi-component force meter removed and the plurality of distortion measuring devices mounted; and an axle multi-component force data creating process for creating axle multi-component force data 9 on the basis of the transfer function model identified in the transfer function model identification process on the basis of data of the distortion measuring devices acquired in the vehicle actual traveling process.
