基于直接CAD几何模型的辐射场生成技术研究及应用
Research and Application of Radiation Field Generation Technology Based on Direct CAD Geometric Model
摘要
Abstract
In this paper,three-dimensional radiation field generation technology based on direct CAD geometric model and its application are introduced.Based on the large-scale parallel unstructured mesh Monte Carlo particle transport method and the direct CAD geometric models,such as Solidworks,Cadmapper,and Autodesk Invernntor,a high efficiency radiation field generation simulation method adapted to electronic components,complex landform geometry and large-area urban environment is proposed.Based on this technique,the numerical simulation of the radiation field of android circuit board,complex radiation source labyrinth environment and nuclear explosion radiation in urban environment building area is realized.The radiation field flux and energy distribution information are obtained in the whole space.The feasibility of this technique in the electronic components radiation effect,the design of radiation source shielding and the simulation of nuclear explosion radiation transient effect is verified.关键词
