摘要
弧形闸门在水利工程中广泛应用,但因其结构、边界条件等均比较复杂,仍未形成比较成熟的设计理论。结合工程实例,基于ANSYS软件对潜孔式弧形闸门进行数值模拟,通过计算弧形闸门在不同工况下的支铰反力、变形、应力以及屈曲失稳情况,分析各个主要构件变形和应力分布规律,对结构的设计和优化提出建议。结果表明:弧形闸门整体刚度、强度和稳定性满足要求,下支臂和门体连接处应力偏大,应进行加固或优化。
Radial gates are widely used in the hydraulic engineering.However,a relatively mature theory has not formed for the complicated structural features,boundary conditions,etc.Combined with the relevant engineering case,the submerged radial gate was numerically simulated based on the ANSYS software.The characteristics of radial gate such as reaction,stress,deformation and stability were analyzed and compared under different control conditions.The results showed that the overall stiffness,strength and stability of the gate meet the requirements,but the stress concentration is obvious at the joint of the lower arm and the door body,where the phenomenon should be strengthened.
