为研究水力自控翻板闸的水动力矩对闸板过流平稳性的影响,采用ANSYS软件的VOF模型计算了某翻板闸过流时的动水压力,并对动水力矩进行了精确计算。结果表明：闸板顶面上半部分形成有利于闸板平稳的顺时针力矩,大小为3169N·m,而顶面下半部分形成破坏闸板平稳的逆时针力矩,大小为2553 N·m；闸板底侧面形成有利于闸板平稳的顺时针力矩,大小为1915 N·m,而背面和顶侧面形成的力矩很小。因此闸板顶面和底侧面所形成的动水力矩对闸板过流平稳性起决定作用。

In order to study the effect of hydrodynamic moment of hydraulic auto-controlled tilting gate on its stability, the hydrodynamic pressure of a practical hydraulic auto-controlled tilting gate is calculated by finite element software ANSYS when it is overflowed by means of the VOF model, where the hydrodynamic moment is calculated accurately. The results show that the clockwise moment of 3169 N·m is formed at the upper part of the tilting gate top, which is beneficial to the stability of the tilting gate. However, the counterclockwise moment of 2 553 N·m is formed at the lower part of the tilting gate top, which is unfavorable to the stability of the tilting gate. The clockwise moment of 1915 N·m that is beneficial to the stability of the tilting gate is formed at the bottom side of the hydraulic auto-controlled tilting gate. While the moments formed at the back and top sides are very small. Therefore, the hydrodynamic moments formed at the top and bottom sides of the tilting gate play a decisive role in the stability when the tilting gate is overflowed.
