Abstract

The invention discloses a magnetic-field forward modeling system for a three-dimensional moving object. The magnetic-field forward modeling system comprises a three-dimensional modeling module used for establishing a three-dimensional model of a magnetic object, a printing and pre-processing module, a printing control module and a magnetic-field forward modeling module. A magnetic-field forward modeling method comprises the following steps of: establishing the three-dimensional model of the three-dimensional moving object through the three-dimensional modeling module, and storing data of the three-dimensional model as an STL file; slicing the three-dimensional model through the printing and pre-processing module, and generating a G-code file; decoding the G-code file through the printing control module, and getting an interpolating point on a printing path; and completing magnetic-field forward modeling by calculating the magnetic-field effect of magnetic dipoles and superposing the effect of each magnetic dipole. According to the magnetic-field forward modeling system and the method disclosed by the invention, operation steps are simple, and time needed for forward modeling and internal storage are independent of complexity of a motion mode and motion.

Description

technical field [0001] The invention relates to the technical field of magnetic field forward modeling, in particular to a magnetic field forward modeling system and method for a three-dimensional moving object. Background technique [0002] The magnetic field forward modeling methods for three-dimensional magnetic objects can be divided into analytical methods and numerical simulation methods. For three-dimensional magnetic sources with regular shapes and distributions, analytical methods can be used to obtain the analytical solution of the magnetic field distribution; for magnetic sources with complex shapes and distributions, calculation The analytical solution of the magnetic field is relatively difficult, and it needs to be calculated by numerical simulation. The finite element method is one of the commonly used numerical simulation calculation methods at present. [0003] A three-dimensional magnetic object can be considered as a combination of a large number of basic ...
