  • Flexure life estimating method, wire harness designing method and program thereof
    Patent number: 6839642
    Abstract: Diameters and the number of respective wires are inputted, and a diameter of a virtual wire formed by converting a wire bundle to a model through a predetermined arithmetic expression derived from rule of thumb, and based upon this, a flexure life estimating process of the virtual wire is carried out. It is possible to easily estimate the flexure life and also to estimate the flexure life and obtain the results immediately after an application subject and a wire harness to be placed have been designed; thus, it becomes possible to shorten the developing period.
    Type: Grant

  • Bend test for a wire harness and device for such a test
    Patent number: 6494104
    Abstract: The invention provides a method of simulating and estimating the minimum lifetime under repeated bending for a wire harness containing a plurality of electrical cables, by applying a compact and lightly equipped device. To this end, representative electrical cables, contained in the wire harness, are subjected to flexing and stretching until they fail under repeated bending, so that the number of bending cycles is obtained for each representative electrical cable. The minimum lifetime for the wire harness can then be estimated on the basis of the shortest cable lifetime that can be found among all the representative electrical cables tested.
