摘　　要：针对九甸峡水利枢纽偏心铰弧形闸门的工作特点,精细模拟了弧形闸门的空间有限元模型,开发了基于ANSYS的动水压力求解模块,通过不同工况的结构动力计算,研究了弧形门的自振特性,并根据计算结果提出了一些有益的建议.According to the operating characteristic of eccentric-hinge radial gate which is located in jiudianxia hydro-junction, the 3D-FEM MODEL is simulated accurately. Based on ANSYS, the model for solving hydrodynamic pressure is developed. According to the results of structural dynamics in different work condition, the characteristic of self-oscillation of eccentric-hinge gate is studied and consequently some useful advice is advanced at last.
