We examine the application of the static condensation method in reducing the dimension of the resolving equations in calculating the natural frequencies and modes of turbine blades of complex geometric configuration on the basis of three-dimensional finite element models. We show the influence of the number of active nodes on the calculation accuracy and time for examples of the solution of test and real problems.
