Analysis And Optimal Design On Static Load And Dynamic Property Of Plane Steel Gate

The plane steel gate is one kind of steel gates the most early and widely steel gate applied in water power engineering. The plane gate is widely used in release water system, generate electricity system, irrigation system and ship system and so on owing to its following advantages: its structure is briefness;it is convenient in making, installing and maintaining;and it is inter change.The plane steel gate is a kind of structure that has strong space effect;space finite element analysis technique is a modern calculating method, which can describe the entire work effect of the space structure. In the process of practical operation of plane gates, the vibration of plane gates often occurs when plane gate is opened or closed or part-opened, and sometimes even under the completely closed condition. Under some situations, the vibration of plane gate is serious that the dynamic failures of plane gate. So it is indispensable to analyze the dynamic properties of plane gate considering liquid-solid coupling effect. Compared with traditional design method, optimization design may speed and upgrade the design. Optimization design can save project investment on economy and bring great benefit.This paper analyze the static properties of plane steel gate, and analyze the dynamic properties considering liquid-solid coupling effect under different load case, using software ANSYS based on APDL language. On this foundation, optimum modal is founded and static and dynamic optimization are analyzed using ANSYS optimization modular. The example appears that the model is reasonable and the optimum result is feasible. The conclusion in the article is played a guiding role in the design of plane steel gate.
