Abstract: The dynamic and static stress values of the high-head arc-shaped working gate were tested under conditions close to the design head. The test results showed that the dynamic and static stresses were both less than the allowable stress. Comparative analysis found that the finite element analysis cal ⁃ culation results were basically consistent with the test results and most of the numerical values were in good agreement. However, there were differences between the test values and the calculated values at some positions. This was because the actual operating boundary conditions of the arc-shaped gate were more complicated than the theoretical boundary conditions due to the manufacturing errors and installa ⁃ tion errors. At the same time, the finite element calculation model was a simplification of the actual situa ⁃ tion of the gate. Therefore, the stress distribution in the arc-shaped gate obtained under test conditions was more reliable than the theoretical calculation values.

摘要： 在接近设计水头工况下，测试了高水头弧形工作闸门动静应力值。测试结果表明，动静应力均小于许用 应力。通过比对分析，有限元分析计算结果与测试结果趋势基本一致，大部分数值吻合性较好，但部分位置的测 试值与计算值存在差异。这是因为弧形闸门的制造误差、安装误差等造成实际运行工况边界条件比理论边界条 件复杂，同时，有限元计算模型是闸门实际状况的简化。因此，弧形闸门测试工况下得到的应力分布比理论计算 值更为可信。
