Abstract
The extended kalman filter is applied to the simultanious identification of flexual rigidity and tension of cables. The one degree of freedom model reduced to first or second order natural frequency mode is used as the mathmatical model of cables on the extended kalman filter. The approximate formula proposed on the practical formulas of the vibration method is used on the relation between natural frequency and cable tension and flexual rigidity. The calculated response values obtained by the same order model and finite element model are first used and the effecs of the method are confirmed. Next, the experiment is carried out by using Al plates as cable spcimens and the effecs of the method are examined.
