水流作用下水利工程闸门的动力特性研究

Study on the Dynamic Characteristics of Water Conservancy Engineering Gates under Action of Water Flow

在水利工程中,闸门用于控制水流和调节水位,但传统模型无法准确描述闸门的复杂响应。为此,研究利用流固耦合模型,分析水流作用下闸门的动力特性。结果显示,当开度为0.4时,振型云图表现出复杂的模式,闸门的下半部分呈现出更为明显的振动;与传统模型相比,研究模型在水深100 m时的最大拉应力在0.78~2.7 MPa之间,表明研究模型可为水利工程闸门的设计和优化提供重要的参考依据。

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.
