Problems solved by technology

However, sometimes, due to some reasons, the actual measurement cannot be carried out, especially at the beginning of the design, and the estimation cannot meet the accuracy requirements. Give a more accurate calculation or simulation of the magnetic properties of the spacecraft
In view of the fact that there is currently no feasible magnetic simulation method for spacecraft, the inventor finally developed a method that can simulate the magnetic properties of spacecraft with high precision and fast speed after many efforts

Embodiment Construction

[0028] Hereinafter, the present invention will be further described through specific embodiments in conjunction with the accompanying drawings. The accompanying drawings are only for the purpose of illustration, and are not intended to limit the scope of protection of the present invention. The magnetic simulation method of spacecraft of the present invention comprises the following concrete steps:

[0029] 1) Obtain the initial magnetic test data of the spacecraft components

[0030] Set the components of the spacecraft part on the center of the magnetic test platform. There are three three-component fluxgate magnetometer probes arranged in a straight line at equal intervals outside the magnetic test platform. The magnetic test platform is rotated from 0-360° every 10° by Three three-component fluxgate magnetometer probes respectively acquire 36 sets of test data, each set includes 9 values, and the magnetic test data are recorded by the magnetic field data acquisition system...

Abstract

The invention discloses a method for simulating magnetism. The method comprises the following steps of: acquiring initial magnetic test data of parts and components of a space ship; building a multi-dipole model of the parts and components of the space ship; establishing a magnetic test simulation system background database of the parts and components of the space ship; establishing a three-dimensional interactive system; and carrying out magnetism simulation of the space ship and other steps. In the method disclosed by the invention, the error introduced in the multi-dipole model is less than 5%, the time for establishing a model by using each group of data is 0-I minute, the operating rate of an improved algorithm is improved greatly, and thus, time requirement of modeling is met.

Description

technical field [0001] The invention belongs to the field of spacecraft magnetic simulation, and in particular relates to a simulation method of spacecraft magnetism, which can be directly applied to spacecraft magnetic simulation and magnetic test. Background technique [0002] For spacecraft in low and medium orbits, there is generally a requirement for magnetic control to eliminate the influence of magnetic interference torque during its service. For individual spacecraft that undertake magnetic measurement tasks or carry magnetically sensitive instruments, the requirements for magnetic control are often more stringent. At present, the commonly used method is to measure the magnetism of the units or parts that may have potential effects one by one, so as to evaluate the magnetic influence on the entire spacecraft or estimate the magnetic properties of the spacecraft based on the magnetic properties of the units or parts, and sometimes use the method of measuring the magne...
