成果简介	NOVELTY - The method involves constructing initial finite element models of composite structures in the form of inertia and stiffness matrices. Correction parameters are grouped. Modal tests are conducted to determine frequencies and shapes of natural vibrations. The initial calculated models of structures are corrected as a result of solving the problem of minimizing the difference between the calculated and experimental natural frequencies. The initial finite element models are supplemented with internal and external corrective elements that determine change in characteristics of models and external connections based on test results. Stiffness matrices are corrected from solution of the optimization problem under condition of minimal difference between natural frequencies and experimental values. Damping matrices are constructed using hypothesis of E.S. Sorokin and condition of closeness of the generalized damping coefficients to the values found experimentally. USE - Method for correcting calculated dynamic models of structures based on test results.
