Study on the Dynamic Characteristics of Water Conservancy Engineering Gates under Action of Water Flow
In hydraulic engineering,the gate is one of the important hydraulic structures,which is used to control water flow and regulate water level.However,traditional models cannot accurately describe the complex response of gates.Therefore,this study utilizes a fluid structure coupling model to analyze the dynamic properties of gates.The results show that when the opening is 0.4,the modal nephogram shows a complex pattern,and the lower part of the gate shows more obvious vibration.Compared with the traditional model,the maximum tensile stress of the study model at 100 m water depth is between 0.78～2.7MPa.In conclusion,the study model provides an important reference for the design and optimization of hydraulic engineering gates.
