Radiation-shielding method of space electronic equipments and its software

A radiation-shielding method of space electronic equipments was researched, and its complicated calculating process was made into program by using computer aided design(CAD) technology and other developing software. The information from the files generated by the professional circuit board software Candence was extracted, and the circuit board models were created efficiently and automatically by using the secondary development function of the three-dimensional CAD technology. The dose point-s coordinates in the model were conveniently and automatically acquired and stored with the computer interactive technology. The background parameters were received from the software interface and the final report was created through the program automatically, by using the Visual Basic for application of the office software. Finally, the radiation shielding analysis software successfully functioned in the calculating of the cumulative space electronic particle dose value in different directions and positions, and in different structures and layouts of the space electronic equipments. Consequently, the reference and proof were provided for the electronic equipment structural anti-radiation design.
