The definite conditions of the potential flow problem of flow fields are established,and the total velocity potentials are calculated. The surface panel method is introduced to discrete grids,and the resultant force on any floating body from flow field is obtained by numerical calculation. A simplified model is proposed,and the law of hydrodynamic coefficients affected by angles and gaps is obtained. When the floating unit’s gap is small,the angle makes great influence on hydrodynamic coefficients,besides there is an optimum angle. As the floating unit’s gap is large, the influence made by the angle on the hydrodynamic coefficients is not significant any more,while the phase relationship of the gap and wave appears remarkable. 【总页数】6页(P896-901) 【作 者】李珂翔;张合;马少杰 【作者单位】南京理工大学 智能弹药技术国防重点学科实验室，江苏 南京210094;南京理工大学 智能弹药技术国防重点学科实验室，江苏 南京210094;南京理工大学 智能弹药技术国防重点学科实验室，江苏 南京210094 【正文语种】中 文 【中图分类】O352 【相关文献】 1.深海多体式浮式结构物稳性研究中浮态参数计算 [J], 桑松;李华军 2.考虑整车的刚柔多体全浮式驾驶室县置系统参数优化设计 [J], 朱祝英;马力;张宇龙;李媛 3.深海多体式浮式结构物浮态求解 [J], 桑松;徐学军 4.整车刚柔多体全浮式驾驶室悬置隔振仿真 [J], 宋发宝;马力;张宇龙;朱祝英 5.H型浮式垂直轴风力机刚—柔耦合多体动力学建模及仿真 [J], 刘利琴;赵海祥;袁瑞;黄鑫;李焱 因版权原因，仅展示原文概要，查看原文内容请购买 本文来源：https://www.wddqw.com/doc/405f9c9abaf3f90f76c66137ee06eff9aef849ff.html
