Research on the Radial Gate Fluid-Structure Coupling of Hydraulic Steel Gate

Abstract:

With the rapid development of China's water conservancy decades, the application of hydraulic steel gate demand is increasing. Among the many types of hydraulic steel gate, the radial gate because of its closed orifice area, pier height is small, over-water conditions are good, open and close rapidly, less embedded parts, etc., are a very wide range of applications. But the survey found that there are many curved steel gate accident in the history of its application. Most accidents are caused due to the instability of the arm, the ultimate reason is the traditional design methods flawed. According to the traditional method of checking the experience plus the theoretical design out of the gate structure, the safety factor is too large, but the overall stress distribution is very uneven, resulting in the investment project is too large, it is difficult to ensure the safe operation of the whole structure. Therefore, it is necessary for radial gate design method to improve it. In this paper, based on the continuum topology optimization theory, combined with structural finite element analysis software, representing a new systematic method of designing curved steel gate.
