Abstract

The hydraulic test model was built to investigate the fluid-induced vibration of plane gate by changing the gate opening and flow rate respectively. The flow field near the gate was measured with the PIV system while the gate structure was measured with 8 channels high speed vibration acquisition system In the experiments, the dynamic distribution characteristics of the flow field around gate and dynamics parameters of the gate structure were measured. The results show that the gate opening and flow rate affect the flow-induced vibration of gate directly. Gate vibration shows asymmetric and aperiodic coupling vibration characteristics. When the flow field interacts with gate, the flow field near the gate is further disturbed. The changes of the corresponding flow boundary conditions result in the downstream fluid showing complex turbulent motion.
