摘要
讨论了吉林台一级水电站弧形闸门的工作特点,建立了水体和闸门耦合作用的求解方程,导出了可用于弧门挡水面的动水压力附加质量的公式,研究和建立了弧形闸门的精细组合有限元模型,计算和分析了闸门在不同开度和不同水头时的自振特性,并根据计算和试验结果提出了有益的建议。
This paper discussed the working features of the Jilintai radial gate sluice, built the derivation equation of water body and gate sluice coupled function, deduced the water pressure and quality formula using for watersupporting section of radial gate, researched and built limited parameter model, calculated and analyzed the selfvibration characteristics of the sluice in different aperture and water head. The suggestions were put forth according to model test results.
