Vibration has serious effects on working condition of hydraulic gate. The vibration characteristics, such as natural frequencies, modal damping and modal shape, of a plane gate with violent vibration in the outlet of inverted siphon are obtained by experiment and analysis with hammer excitation method. The results show that the distribution of natural frequencies of the hydraulic gate in a wide range is the main cause of flow-induced vibration. The first natural frequency of the hydraulic gate in vertical direction is lower than in water flowing direction and in transverse direction, which indicates that the modal stiffness of the hydraulic gate in vertical direction is significantly lower than the other two directions.
