摘要
针对舰船消磁过程对磁场推算法精确、快速、通用性好的要求,根据已有的磁场推算法提出了单分量椭球阵列法的建模思想,该方法是用单分量椭球阵列产生的调和函数组合来模拟舰船磁场,通过船模实验,验证了该方法具有较高的近距离磁场推算精度,对不同船型有较好的通用性,且运算速度较快,满足工程实用要求。
Aim at the requirements that the vessel's magnetic field should be continued with accuracy, speediness and applicability in degaussing process, the uniaxial magnetized ellipsoid array model was presented based on the method which had been presented previous. Through this model, the vessel's magnetic field was simulated by a series of Laplace's functions. By vessel' s model experiments, the method was proved that it could continue vessel' s magnetic field between the planes in a narrow range of distances with absolute accuracy, and could be applied to different kind of vessels, and the results satisfied engineering requirements.
