摘要
对水平时谐电流元提出新的镜像法求解方法,对舰船采用水平时谐电流元进行建模,并应用改进的镜像求解法来研究腐蚀相关轴频电场在均匀、线性各向同性半无限大的导电介质中所产生的电场强度。通过对水平时谐电流元的整体镜像,结合数值方法求解海水中的矢量磁位A,并应用矢量磁位与电场强度的关系对水平时谐电流元在海水中任一点产生的电场强度进行推导。最后对某一海水深度产生的电场强度通过实验验证和相同条件下的Matlab仿真进行结果对比,验证其正确性和实用性,并为海上舰船电场测量提供理论基础。
Through using horizontal harmonic current makes model for naval ship to put forward a new modified method of mirror image , which is based on the predecessors＇ research achievement of the horizontal harmonic current researehful method and applys the modified method of mirror image to study the shaft-rate electric field that is related to the corrosion in the half infinite conductive medium of the homogeneous, linear and isotropic field. It will solve the vector magnetic potential that is named A in seawater and apply the relationship between the vector magnetic potential and electric field intensity to deduce the electricity intensity expression of certain point through the horizontal harmonic current＇s overall image. Finally, it will compare the result of the electricity intensity on certain depth, which is produced by experiment and simulation of Matlab in and provide theoretical basis for marine the same environment, to verify the correctness and practicability, ship electric field measurement.
