中文摘要：
针对浅水动态柔性管/缆系统的附件——中水浮拱的浮力舱,介绍其结构特点和功能等,并给出其基本参数;用ANSYS分析浮力舱结构强度,得到壁厚变化对浮力舱的强度和质量影响的一般规律;研究浮力舱在破舱后对中水浮拱整体功能的影响;总结内部隔板与外舱体连接处的倒角半径和浮力舱应力变化曲线,给出最佳倒角半径范围.研究结果可以提高中水浮拱的安全可靠性和设计水平.
英文摘要：
As to the buoyancy tanks of middle water arch which is the accessory of the dynamic flexible pipe /cable system used in the shallow water,the structure features and functions are introduced and the basic parameters are given; the structural strength of the buoyancy tanks is analyzed by ANSYS,and the general rule of the effect of wall thickness change on the strength and mass of buoyancy tanks is obtained;the effect of buoyancy tank damage on the overall functionality of middle water arch is studied; the curve of buoyancy tank stress and chamfering radius of the connection between internal baffle plate and outer hull is summarized and the scope of the best chamfering radius is given. The research results can improve the safety and reliability and the design level of the middle water arch.
