Ya., Registration Date 31-01-2006 Organization A. Podgorny's Institute of Mechanical Engeneering Problems of the National Academy of Science of Ukraine popup.description2 A technique of refined analysis of strength and development by mass of the assembly "scroll-stator" of a hydraulic turbine; the technique of analyzing the statics and dynamics of compound constructions of the flow channel of a hydraulic turbine with account of complex loading, and conditions of fastening in concrete, etc. have been developed. A technique of harmonic analysis has been developed for solving the forced oscillations problem by expanding the displacements by natural modes for this class of constructions. The natural oscillation frequencies and modes are found by the FEM in combination with Fourier series expansion of sought for displacements and loads. Numerical analysis of statics and dynamics of real elements of constructions of the flow channel of hydraulic turbines at different operation regimes have been carried out. Application - power machine building. Product Description popup.authors popup.nrat_date 2020-04-02 Close
