摘要： PROBLEM TO BE SOLVED: To provide a current moment analysis device capable of more accurately determining a current moment compared to conventional cases. SOLUTION: When a measured vessel 5 is made to pass through a neighborhood, a zero cross-point of an output waveform of a submerged electric field sensor 2 is detected. Based on positional information of the submerged electric field sensor 2 and positional information of the measured vessel 5 obtained during detection of the zero cross-point, an intermediate position of a current source of the measured vessel 5 is led out, and based on the intermediate position and the position of the current source (- side), a current source interval L of the measured vessel 5 is determined. A peak-to-peak value Va of the output waveform of the submerged electric field sensor 2 is stored. Next, as the same condition, the output waveform of the submerged electric field sensor 2 at a current value I [A] is led out by simulation, and a peak-to-peak value Vb at that time is determined. In the condition, a current value I=Va/Vb achieving the situation where the waveform is the peak-to-peak value Va is determined. Thus, by determining the current value I of the measured vessel 5, the current moment (L×I) of the vessel is determined. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method for estimating permanent magnetism of a hull, which is capable of estimating permanent magnetism of the hull when a magnetic field is applied to the hull before degaussing is performed. SOLUTION: A specimen made of steel which is the same as the steel of the hull to be degaussed is created (ST1), and magnetization characteristics are measured by changing the magnetic field applied to the specimen (ST2). From the measured magnetization characteristics of a plurality of patterns, a Preisach's distribution chart for the steel is created (ST3). A hull numerical calculation model corresponding to a well-known numerical calculation method is created (ST4), and an applied magnetic field for each element is calculated (ST5). A Preisach's diagram corresponding to the applied magnetic field calculated is created for each element (ST6); permanent magnetism of each element is calculated based on the Preisach's distribution chart and the Preisach's diagram (ST7); permanent magnetism around the hull is estimated by the numerical calculation method based on the estimated value of permanent magnetism of each element (ST8); and an estimated value of permanent magnetism around the hull after magnetic processing is output (ST9).

摘要： PROBLEM TO BE SOLVED: To provide a magnetic measuring system capable of accurately measuring magnetic fields in a north-south direction, an east-west direction, and a vertical direction even under an oscillating environment. SOLUTION: In a magnetic measuring system comprising a triaxial magnetic sensor and an attitude sensor for measuring oscillations of the triaxial magnetic sensor and converts measurement data of a magnetic sensor into magnetic fields in a north-south direction, an east-west direction, and a vertical direction through a use of oscillation information acquired by an attitude sensor, an offset, orthogonality, and sensitivity of the triaxial magnetic sensor and displacements in axial parallelism between the attitude sensor and the triaxial magnetic sensor are corrected so as to minimize magnetic field variations in a north-south direction and variations in all magnetic forces. These correction values are used to alter measurement data of the triaxial magnetic sensor into magnetic fields in a north-south direction, an east-west direction, and a vertical direction.
