摘　　要：针对水下无人潜航器(UUV)磁场分布特性的研究需求,利用有限元仿真软件COMSOL Multiphysics对UUV的磁场分布进行建模和仿真。分析UUV内部磁场来源及分布情况;对比分析磁偶极子理论计算与COMSOL磁场建模仿真,探讨利用COMSOL软件模拟方法开展磁场建模的可行性;运用COMSOL仿真软件,构建UUV几何模型,求解分析UUV平台干扰磁场分布特性。建模和仿真结果表明,利用COMSOL仿真软件实现磁偶极子建模是正确可靠的,UUV平台中后部磁感应强度最强,艏艉处磁感应强度最小,约为20 nT,为UUV平台的磁传感器安装位置和低磁性优化设计提供了依据。In view of the demand for the magnetic field distribution characteristics of unmanned underwater vehicle(UUV),this paper used the finite element simulation software COMSOL Multiphysics to study the magnetic field distribution of UUV for the first time.Firstly,the source and distribution of the internal magnetic field in UUV was analyzed;then,the magnetic dipole theoretical calculation and COMSOL magnetic field modeling simulation were compared and analyzed,and the reliability of magnetic filed modeling using COMSOL software simulation method was discussed;finally,the COMSOL simulation software was used to build a UUV geometric modeling and analyze,the distribution characteristics of the interference magnetic field of the UUV platform.The modeling and simulation results showed that the magnetic dipole modeling using COMSOL was correct and reliable;the magnetic induction intensity of the rear part of the UUV platform was the strongest;the magnetic induction intensity at the bow and stern is the minimum,about 20nT,which provided a basis for the installation position of magnetic sensor and low magnetic optimization design of UUV platform.
