Test and Research on Flow-Excited Vibration of Working Gate of Upper Stream Pumping Unit in Qingcaosha Reservoir

摘要：

Through using hydro-elasticity similar model we had this research on flow-excited vibration of working gate of upper stream pumping unit in Qingcaosha reservoir, elaborating on the similar principle and mode-making method of gate vibration test. According to test on flow-excited vibration of gate with two working conditions of water diversion and drainage under different combination of upper and downstream water conditions, we got the hydrodynamic pressure load statistical characteristics, pulsating pressure coefficient as well as structural vibration acceleration, dynamic displacement and stress parameters working on gate body. We had discussed about the effect the draining grating before the gate and lateral opening boundary conditions exert on fluid state and gate vibration, offering scientific proofs for making operation regulations and safety evaluation.
