| Abstract: | Based on the transient dynamic analysis of fluid-solid coupling,the mode of vortex hydraulic pulsation in the draft tube of bulb tubular turbine is studied herein,and then the wave pattern of the vibration and the structural response impacting on the powerhouse and its foundation are also analyzed.Finally,the method of the simplified simulation of the pulsating pressure load in the draft tube is studied,so as to provide a reference for the structural analysis and the relevant design study on the hydropower plant installed with bulb tubular turbine-generator units. |
