Abstract
A radiation effect shielding calculation method based on a three-dimensional spacecraft model is provided. The method includes obtaining the three-dimensional spacecraft model; dividing a 4π space irradiation environment into meshes to obtain space irradiation vectors corresponding to the meshes respectively; setting one or more analysis points at each target model component; inputting the space irradiation vectors to the three-dimensional spacecraft model to obtain a three-dimensional distribution of actual shielding at each analysis point; obtaining a three-dimensional distribution of an equivalent aluminum shielding thicknesses according to equivalent thickness conversion for different materials; calculating residual irradiation effect values of the three-dimensional distribution of the equivalent aluminum shielding thicknesses of each analysis point to obtain corresponding detailed irradiation data; and performing information post processing and integrating in all directions to obtain a corresponding total radiation effect value.
