Abstract

In this paper, based on the fluid-structure coupling theory, the wheel of the bulb hydraulic turbine was done the transient dynamic analysis by using ADINA software, with the semi-implicit method for solving pressure coupled equations inflow field calculation and the dynamic mesh technology. And the modal analysis was done with Lanczos Iteration algorithm to the bulb hydraulic turbine, separately calculating the natural frequencies and the mode shapes of the wheel in the air and water medium. The article got the dynamic characteristics of bulb tubular turbine under considering fluid-structure coupling.
