Originální abstrakt

This thesis is concentrated on mathematical modeling of high frequency pulsations in pump turbines, which are the source of high-cycle continuous stress of the spiral casing cover, wicket gates and runner. The problem is solved by transfer matrix method. F-A char. and MS Excel programs have been used for data processing. Final results are presented by graphs of frequency-amplitude characteristic depending on running speed of motor, and plots of the pressure mode shape in selected phase shifts. Modeled variants are those of wheels with 7; 9 blades and 7 blades and 7 semi-blades. The number of distributing blades is 20..
