Optimization of Free Frequency Spectrum for Turbine Blade Packs [in Russian]
ЮРИЙ С. ВОРОБЬЕВ, АНАТОЛИЙ П. ФИЛИППОВ
Abstract
The problem of optimum selection of constructional and material parameters of turbine blade packs has been solved in the paper. The region of parameter variation is bounded due to strength and constructional requirements. The preset spectrum of free vibration frequency is the objective function. Nonlinear programming methods have been adopted for the solution of the problem. Theoretical considerations have been illustrated with an example of calculations.
