Solenoid magnetic field simulation capability analysis based on current inversion
In order to analyze the simulation capability of the solenoid to the ship's magnetic field,an equivalent magnetic dipole array model is used to calculate the solenoid magnetic field.Based on the empirical setting of solenoid configuration parameters,combined with the measured data of the ship model magnetic field,the least squares method was used to invert the solenoid current based on the plane magnetic field vector inversion solenoid constant current,the planar magnetic field scalar inversion solenoid constant current,the planar magnetic field vector inversion solenoid time-varying current,and the planar magnetic field scalar inversion solenoid time-varying current and other four methods.The relative error of the solenoid magnetic field vector and scalar and the ship model magnetic field vector and scalar generated by the four inversion methods is calculated.The simulation capabilities of different inversion methods are compared and analyzed,and finally the current inversion method of solenoid simulating the ship's magnetic field is given.
