Patent ID: 7403829

Claim:
An estimating method of a wire harness for estimating a wiring property of the wire harness by a finite element method (FEM) and estimating an analysis result on a screen of a display unit, the wire harness having a constrained base end and a distal end having a connector constrained to a connector base, said estimating method of the wire harness, comprising the steps of: displaying, on the screen, a virtual three-dimensional shape image of the wire harness including the connector, using computer-aided design (CAD) data formed for designing the three-dimensional shape and a condition setting screen for setting one part of analysis conditions, which is not included in said CAD data, of a property, a shape, a constraining position, and a constraining direction of the wire harness by input operation; recognizing, as a coordinate value of the constraining position, a position on a moving destination of the connector, designated on said virtual three-dimensional shape image; analyzing the wiring shape of the wire harness and a reactive force upon grasping the connector by the FEM under analysis conditions necessary for estimation included in said CAD data, an analysis condition set on said condition setting screen, and the constraining position prescribed by the coordinate value; and displaying, on the screen, the virtual three-dimensional shape image of the analyzed wiring shape including the connector and the analyzed reactive force.
