通过几何比尺１７的阀门段水力学模型试验，测量了在阀门运行过程中三峡船闸输水阀门支铰荷载，并分析了其脉动量的数值及频率特性。成果分析表明：支铰力量值主要由阀门前后压力差及有效受力面积决定；阀门全关时受起始水头作用引起的支铰力是阀门开启过程中支铰最大荷载点；阀门动水关闭可能引起的阀门前后实际作用水头超过起始水头会造成支铰承受更大的荷载，是设计应特别注意的工况。与支铰时均荷载相比，支铰力脉动量较小，其优势频率与门后压力脉动的优势频率较吻合，两者的功率谱密度均表现为具有低频优势分量的宽带噪声谱。
Through the hydraulics model test of the valve section of Geometry Scale 17, the load of the valve support of the Three Gorges ship lock during the operation of the valve was measured and the numerical and frequency characteristics of the pulsation quantity were analyzed. The analysis of results shows that the value of the supporting force is mainly determined by the pressure difference between the front and the back of the valve and the effective stress area. The supporting force caused by the initial head when the valve is fully closed is the maximum load point of the branch when the valve is opened. May cause the valve before and after the actual head over the initial head will cause the hinge to bear a greater load, the design should pay special attention to the conditions. Compared with the average hourly load of supporting branch, the amount of pulsating branch force is small, and the predominant frequency agrees well with the dominant frequency of pressure pulsation behind the door. The power spectral densities of both show the broadband noise spectrum with dominant component of low frequency.
