METHOD FOR MEASURING LOAD DISPLACEMENT CHARACTERISTIC OF TURNING OPERATION IMPLEMENT AND LOAD DISPLACEMENT CHARACTERISTIC MEASURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To measure a load displacement characteristic even if a turning center of a turning operation implement and a distance from the turning center to a measuring point are unclear.;SOLUTION: The method for measuring a load displacement characteristic of a turning operation implement operated by turning includes: fixing, to a lever 200, a grip 110 having a force sensor for detecting an operating force; setting a measuring point P turning along with the lever 200 at the adjacency of the grip; setting a distance reference point Q fixed to an arbitrary location; measuring, at three or more locations, a distance s between the measuring point and the distance reference point, and an angle θ with respect to a coordinate axis of the force sensor 112; calculating a rotation radius r of the measuring point P based on the distance s and the angle θ; and finding a relation between the load and the displacement of the lever 200 based on the rotation radius r, an operating force f, and the angle θ.;COPYRIGHT: (C)2012,JPO&INPIT
