摘要
针对不平衡启门力对弧形闸门安全启闭的影响,基于某实际工程,建立弧形闸门-启门力-水封整体三维有限元接触模型,引入ADINA接触模型和重启动的方法模拟闸门开度为0时的启门工况,计算出该弧形闸门的最大启门力,并与工程实际检测数据进行比较。同时,在此模型上对不平衡启门力作用下闸门的瞬态动力响应进行计算,分析闸门在不同开度下受不平衡启门力作用而产生的应力和变形。可为弧形闸门的安全启闭和设计提供有益参考。
The normal operation of arc gate is influenced by the imbalanced uplifting force. Taking a practical project for example, a 3D finite element contact model of an arc gate with uplifting force and water seal at the bottom was established based on ADINA. The maximum uplifting force under the opening of 0（being about to open） was calculated by FEM with constraint-function algorithm and restart technique of ADINA, and the results were compared with the testing data. The transient dynamic response of the gate under the imbalanced uplifting force was analyzed respectively to research the stress and stain under different openings, which provides references for safe opening and closing of arc gates and its design.
