An Equivalent Simulation Method of High Power Magnetic Field Radiation Source

Abstract

The present invention provides an equivalent simulation method of a high-power magnetic field radiation source, which includes the equivalent simulation of an AC magnetic dipole array, and realizes that the physical model and internal structure of the high-power magnetic field radiation source are not known. The simple magnetic field distribution measurement results and calculation steps of actual equipment simulate the function of the magnetic field radiation characteristics of high-power magnetic field radiation sources. According to the measurement results of the magnetic field distribution of the actual equipment, the present invention uses the equivalent simulation method of the magnetic dipole array to more accurately simulate the magnetic field radiation characteristics of the high-power magnetic field radiation source. Research provides convenient and accurate methods.

Description

technical field [0001] The invention belongs to the technical field of magnetic field simulation, and in particular relates to an equivalent simulation method of a high-power magnetic field radiation source. Background technique [0002] In order to better study the magnetic field of high-power equipment, it is necessary to obtain the intensity and distribution characteristics of the magnetic field of these equipment accurately. At present, the main means of research on magnetic field sources at home and abroad include actual equipment measurement, physical model measurement and computer simulation. [0003] 1. Actual device measurement [0004] To carry out the research of low-frequency stray magnetic field by means of actual equipment measurement, there must be enough measurement points, and the measurement surface must be large enough. At present, some low-magnetic laboratories in China can carry out the magnetic field measurement of actual equipment on the measurement ...

Problems solved by technology

[0018] The above three methods all have different problems. The actual equipment measurement requires a lot of manpower and material resources. Physical model measurement and computer simulation require physical modeling of the internal structure of the equipment.

In fact, when studying the magnetic field distribution of high-power equipment, we don't care about its internal structure, and high-power equipment often has complex structures, and the modeling difficulty and workload are relatively large.
