实验室自主研发“葫芦娃”机器人在完成自动换装过程中需要倾角传感器对机械臂转动角度进行实时反馈。针对电子元器件耐辐照能力较弱的情况,本文为倾角传感器设计辐射屏蔽装置,利用MCNP程序建立屏蔽装置模型,通过对5个面的辐射通量分析,通过优化各面铅的厚度,减小整个屏蔽体的重量,研究开散热孔对屏蔽体整体性能的影响以及辐射衰减与距离之间的关系,初步验证了本文设计的辐射屏蔽装置作为高辐射场下屏蔽γ射线的模型所具有的合理性。

The independent research and development of the"cucurbit"robot in the laboratory requires the tilt sensor to provide real-time feedback on the angle of rotation of the arm during the automatic dressing process.In view of the weak radiation resistance of electronic components,this paper designs a radiation shielding device for the inclination sensor,and uses the MCNP program to establish the shielding device model.Analyzing the radiant flux of the five surfaces,the thickness of lead on each surface is optimized.The weight of the entire shield is...
