摘　　要：严格按照施工现场对防辐射挖掘机供气系统、驾驶员的视野、防辐射标准及整机重量的作业要求,设计核辐射环境作业挖掘机的供气系统、铅玻璃视窗、影像系统以及驾驶舱屏蔽材料的厚度等。并通过供气系统实验、铅玻璃机械性能实验、视窗大小实验以及利用MCAM软件和MCNP软件联合对驾驶舱屏蔽效果进行建模仿真等,为防辐射挖掘机的设计提供依据。通过详细介绍防辐射挖掘机的设计结构和相关实验研究,为我国核应急和核设施退役装备的研制提供参考。Strictly in accordance with the requirements of gas supply system, drivers＇ visual field scope, the standards of radiation protection and the total weight of excavator in construction site, the gas supply system, leaded glass windows, imaging systems and the thickness of radiation shielding material of cockpit were designed. The design＇s basis for the excavation were obtained through gas supply system experiments, lead glass mechanical performance test, window size＇s experiment and the modeling and simulation of cabin＇s shielding effect by MCAM and MCNE The detailed introduction of the design structure and related experimental study of the radiation excavator could be the reference for the equipment＇s development of the nuclear emergency and in the process of decommissionine of nuclear facilities in our country.
