The identification of stiffness of the blade supports at lateral bending vibrations is considered. A beam model is used for elastic restraint. The target functional is applied in the form of the squared discrepancy between the experimental and theoretical values of deformations. The minimization of the functional is carried out by iterations using the sensitivity apparatus.
