  • Methods and apparatus for calculating routing arrangements for control cables
    Patent number: 7013236
    Abstract: The present invention provides a method for predicting a routing arrangement for control cable without preparing experimental control cables. In the method according to the present invention, characteristics of a control cable to be laid are obtained (S1, S2, and S3). The characteristics of the control cable can be obtained by subjecting a test piece of control cable to a known test (tensile test). Next, a length of the control cable and a condition for connecting the control cable are provided as conditions for a computation (S4 and S5). Then, the given length of the cable, the given condition for connecting the cable, and the obtained characteristic of the control cable are used for a computation model, which was formed by dividing the control cable into a plurality of elements, in order to perform a finite element method, and, thus, a routing arrangement is calculated (S7).
