摘要
Abstract
In the field of deep-sea resource magnetic detection,spatial magnetic field anomalies are detected by sensors and combined with relevant algorithms to determine the spatial coordinates of resources.However,the magneto-mechanical coupling effect of underwater vessels made of ferromagnetic materials leads to changes in the spatial magnetic field as the outer wall is subjected to pressure,thereby affecting detection accuracy.Current research is limited to the effects of internal pressure on magneto-mechanical coupling.Therefore,investigating the influence of external pressure on the spatial magnetic field around ferromagnetic chambers is essential.A method of applying pressure by wrapping with low-magnetic steel was adopted to investigate the magneto-mechanical coupling effect of a marine steel ferro-magnetic chamber under external pressure.The distribution of the fixed magnetic field and the induced magnetic field under the action of the background magnetic field was measured,and the relationship between the induced magnetic field,spatial magnetic field variation,and the direction of the background magnetic field was determined.This study effectively addressed the challenge of applying external pres-sure in experiments,providing new insights into the study of magneto-mechanical coupling effects of ferro-magnetic chambers and offering a reference for adjusting demagnetization currents in deep-sea resource magnetic detection.关键词
