摘　　要：为更好地对潜艇感应磁场进行测量,通过分析感应磁场的产生及测量原理,建立基于地磁模拟的感应磁场测量方法.通过在地磁模拟线圈中通电改变地磁场,根据模拟线圈通电前后潜艇磁场的变化计算感应磁场,从而实现单航向感应磁场的快速测量.实艇测量实验表明,该测量方法可快速、准确测量潜艇感应磁场,在实际的潜艇感应磁场测量及消磁工作中具有重要应用价值.In order to measure the induced magnetic field of submarines more conveniently,a measurement method to the induced magnetic field based on geomagnetic simulation is proposed through analyzing the generating and measuring principle of the induced magnetic field. The geomagnetic field is changed by galvanizing the geomagnetic simulation loops,and then the induced magnetic field is calculated according to the change of the submarines＇ magnetic field before and after galvanizing,which can achieve the fast measurement of the induced magnetic field in a one-way route. The experiment of a full-scale submarine shows that the method can be used to measure the induced magnetic field of submarines fast and accurately and is of important application value in the actual measurement of the induced magnetic field and degaussing of submarines.
