研究了空间电子设备辐射屏蔽分析的方法,利用计算机辅助设计(CAD)技术和软件开发工具,将复杂繁琐的计算过程编写成流程化的程序;利用三维CAD技术的二次开发功能,从Candence软件生成的记录文件中提取出信息,在计算机图形环境中高效自动地生成电路板模型;借助计算机交互技术,实现剂量点坐标的自动提取和保存;利用办公软件个性化设置功能,设计出提取背景信息的接口,实现了最终报告文档的自动生成.开发出的软件最终成功地实现了在不同结构和布局的空间电子设备中,在不同方向和位置上累积的空间带电粒子剂量值的计算,为电子设备结构的抗辐射设计提供了参考和依据.
The method of radiation shield analysis of space electronic equipment is researched. Computer-aided design (CAD) technology and software development tools are used to compile the complex and cumbersome calculation process into a process-oriented program. By using the secondary development function of 3D CAD technology, The generated record file extract information, computer graphics environment in the efficient and automatic generation of circuit board model; with computer interaction technology to achieve the coordinates of the dose point automatically extracted and saved; the use of office software personalized settings designed to extract the background information Of the interface to achieve the automatic generation of the final report of the document.Finally, the software developed successfully in space electronic devices with different structures and layouts, the accumulation of space charged particle dose values in different directions and positions, the calculation of electronic Equipment design of the anti-radiation provides a reference and basis.
