基于SESAM的自航水雷校准天线近海面水动力分析

Hydrodynamic Analysis of Self-Propelled Mine Calibration Antenna Near Sea Surface Based on SESAM

利用DNV开发的三维势流系列软件SESAM,以近海面上浮校准的自航水雷天线为研究对象,GeniE建立浮体模型并进行网格划分,HydroD对浮体水动力参数进行计算,SIMA对浮体在随机波浪作用下的运动进行计算。为验证计算方法合理性,计算了天线在三、四级海况下出水统计概率以及天线外罩在五级海况下承受波浪冲击的能力。本文可为自航水雷在近海面水动力分析提供参考。

Software SESAM of 3D Potential Flow Series were developed by DNV.The research object was the self-propelled mine antenna with the calibration of floating near sea surface.GeniE built the floating body model and meshwork,HydroD calculated the hydrodynamic parameters of the floating body,and SIMA calculated the motion of the floating body under random wave action.To verify the reasonableness of the calculation method,the statistical probability of the effluent of the antenna under three or four sea conditions and the requirement of the random to withstand wave impact under five sea conditions calculated.To provide reference for hydrodynamic analysis of self-propelled mine near water surface.
