摘要： 以北支江水闸项目底轴驱动闸门为依托，针对底轴驱动闸门开闸时不同角度下泄水对闸门产生动水压作用带来的影响进行分析研究，采用流固耦合的方法分析其在动态水流作用下的受力状态。研究表明，闸门转角为70°和75°时，受到的切应力和米塞斯应力最大，此时是最恶劣的工况，建议在实际运行过程中尽量减少在转角70°和75°时的停留时间。
关键词: 底轴驱动闸门, 动态分析, 流固耦合, 恶劣工况
Abstract: Based on the gate of Beizhijiang project which is driven by bottom shaft, fluid-structure coupling analysis method is used to analyze the force statement and the force applying on the gate by dynamic water flow with different angles when the gate is opened. Studies have shown that the shear stress and the Mises stress of the gate reach the largest when the gate opening angles are 70° and 75°, which are the worst working conditions for the gate. It is recommended to minimize the dwell time of the gate at opening angles of 70° and 75° during actual operation.
Key words: gate driven by bottom shaft, dynamic analysis, fluid-structure coupling, severe working conditions
