对求解弧形闸门支铰各反力大小及方向的现行规范和其他一些参考资料,都是采用图解法,而未将水封摩阻力考虑进去。水封摩阻力沿弧线分布,各点的方向和大小不同。根据实践经验证明,水封(参见图1)摩阻力,特别是侧水封摩阻力不可忽略,尤其在高压弧形闸门设计中,它是一个相当大的力,对启闭力的大小和支臂断面的设计都有很大的影响。为此,本文提出了考虑水封阻力影响计算弧形闸门支铰反力的数解法及侧水封摩阻力的计算方法。 (一) 平衡力系计算当弧形闸门开启时,作用在其上面的
The existing norms and other references for solving the magnitude and direction of the reactions of the arcuate gate hinges are all graphic and not the water seal frictional resistance taken into account. Hydrostatic friction along the arc distribution, the direction and size of each point is different. According to practical experience, water seal (see Figure 1) friction resistance, especially the side water seal friction resistance can not be ignored, especially in the design of high pressure arc gate, it is a considerable force on the opening and closing force size and branch Arm section design has a great impact. For this reason, this paper proposes a numerical solution considering the influence of water seal resistance on the calculation of the reaction force of the branch valve support and the calculation method of the side water seal frictional resistance. (A) The balance of force is calculated when the arc gate open, the role of the above
