Abstract:
1. A rotation angle calculating method of a wire harness, in which a rotation angle of the wire harness is calculated at an arbitrary measuring point of the wire harness when the wire harness is deformed from a first shape to a second shape while a fixed point of the wire harness is fixed, the rotation angle calculating method, comprising the steps of: setting a plurality of intermediate points between the fixed point and the measuring point of the wire harness in the second shape, wherein the fixed point, the measuring point and the intermediate points are set as nodes respectively; setting vectors tangent to the wire harness at the nodes of the wire harness in the second shape as node vectors respectively; calculating angles, each of which has a rotation direction, wherein each of the angles is defined between the node vectors at the adjoining nodes; adding the angles to each other so as to calculate a rotation angle having a rotation direction at the measuring point; and recording said rotation angle.
