Title:
METHOD FOR ESTIMATING WORK MACHINE MOMENT
Document Type and Number:
WIPO Patent Application WO/2022/176515
Kind Code:
A1
Abstract:
The present invention accurately measures a moment of a work machine. A work machine is put in a first posture. A first payload computation value, which is the weight of a load imposed on the work machine in the first posture, is acquired. The work machine is put in a second posture. The ratio of the horizontal distance between the position of the center of gravity of a first link member and a base end of the first link member to the horizontal distance between the position of the center of gravity of the load imposed on the work machine and a base end thereof is equal in the first posture and the second posture. A second payload computation value, which is the weight of the load imposed on the work machine in the second posture, is acquired. The first payload computation value and the second payload computation value are compared. If it is determined, on the basis of the results of the comparison of the first payload computation value and the second payload computation value, that the first payload computation value and the second payload computation value differ, the weight of the second link member is changed, and the processes described above are repeated.
