摘要
针对舰艇感应磁场难以快速准确获取的问题,开展了磁场映射法测量横向感应磁场垂向分量的实验验证研究。利用某消磁站缩比物理模型进行实验,分别采用单航向上磁场映射法和地磁模拟法来测量船模的横向感应磁场垂向分量,并与传统的两航向法测量值进行比较。结果表明单航向上磁场映射法精度较高,相对均方根误差为8. 13%,且在工程实践中较传统方法更高效,为进一步推广单航向上磁场映射法测量舰艇感应磁场提供了依据。
In this study,the difficulty in obtaining the induced magnetic field is addressed.A research was carried out to verify the magnetic mapping method for measuring the vertical component of the athwartship-induced magnetic field.An experiment was implemented on a physical scaled model of a degaussing instrument to measure the athwartship-induced magnetic field of the ship model by single-course magnetic mapping method and geomagnetic simulation method.This method is compared with the traditional two-course measurement method.The results show that the magnetic mapping method with single course has a very high precision,and its relative root mean square error is 8.13%.This indicates that the single-course magnetic mapping method is more efficient than the traditional method in practical engineering applications,and thus,it can be commercialized.
