<P>PROBLEM TO BE SOLVED: To provide a hanging device capable of calculating a barycentric position of an object in a state of hanging the object. <P>SOLUTION: A hanging device 100 comprises: a hanging part 10 that is movable in a state of hanging an object; a support part 20 for supporting an object A; multiple span wires 31 to 34 for connecting the hanging part 10 with the support part 20; an operation part 60 for controlling a moving speed of the hanging part 10 and causing free vibration in a horizontal direction to the object A; and a computing part 70 for calculating a barycentric position of the object A. The hanging device 100 is configured so that a distance w2 between supporting points of the span wires 31 to 34 on the side of hanging part 10 differs from a distance w1 between supporting points on the side of the support part 20 in a vibration direction of the object A. The computing part 70 calculates a barycentric position of the object A in a vertical direction based on weight of the object A, a vibration period of free vibration caused to the object A, a hanging distance between the hanging part 10 and the support part 20, the distance between supporting points on the side of the hanging part 10, the distance between supporting points on the side of the support part 20 and a moment of inertia about the barycenter of the object A. <P>COPYRIGHT: (C)2012,JPO&INPIT |
