| Abstract: | |
|
For the first time, a method for frequencies and form determination of hydroelastic natural oscillations of hydroturbine head covers has been developed. Eigenmodes of the structure oscillations in fluid were investigated as a series in terms of vibration eigenmodes in vacuum. Hydroelasticity problem solving was obtained by making use of singular integral equations and a finite element method. A numerical analysis was carried out. |
