So how to solve the flow-inducedvibration response and the dynamic characteristic , has been the most important problems that should be solved in the design of gate.
It is of great signification for instructing tainter gate design to study mechanism of gate flow-inducedvibration, discuss rule of gate vibration and give out controlling criteria.
研究闸门流激振动机理，探讨闸门振动规律，给出控制判据，对指导钢结构闸门设计是具有非常重要的意义。
