The invention relates to the technical field of
hydropower station maintenance, in particular to a
deep hole radial gate fluid-structure interaction
vibration control and improvement method. A monitoring point
assembly is arranged on a deep-hole arc-shaped service gate and a dam, vibration, stress,
water flow characteristics and operation state data under different working conditions are collected, transmitted in real time and displayed; evaluating the influence of vibration on the gate structure and dam connection safety; and according to vibration inducements obtained through analysis, a numerical
simulation analysis scheme is adopted, and corresponding gate vibration reduction measures are adjusted. Monitoring points are arranged on a gate main beam, a supporting arm, a lifting lug and a dam, vibration, stress, hydraulic jump and jet data are comprehensively collected, and the authenticity and comprehensiveness of the data are ensured. A
single factor analysis method and FSI modeling are adopted, vibration contributions of factors such as water seal
water leakage and bottom edge hydraulic jump are quantified, finally, according to vibration inducements, the balance weight, the bottom
edge type and the water seal structure are optimized, and the vibration reduction effect is verified through numerical
simulation.
