【摘要】:电子器件的抗辐射防护和热防护是核救灾机器人安全运行的前提。为了使核救灾机器人具有更强的可靠性和更长的工作时间,以机器人驱动核心部件——电机驱动器为研究对象,从提高自身耐辐射性能、增强屏蔽以及热防护角度出发展开研究:去除和替换辐射敏感元器件,紧密式排布安装驱动器以提高空间利用率;基于蒙特卡罗方法模拟屏蔽材料的组成成分与屏蔽效果关系;引入相变材料延长驱动器的工作时间。以上措施确保电子器件在环境温度100℃、辐射总剂量为4.95×10~5 rad情况下可以正常运行98 min,满足核救灾机器人的基本工作要求。
[Abstract]:The anti-radiation protection and thermal protection of electronic devices are the premise of the safe operation of the nuclear disaster relief robot. In order to make the nuclear disaster relief robot have stronger reliability and longer working time, the research object is the motor driver, which is the core component driven by the robot. From the point of view of improving its radiation resistance, enhancing shielding and thermal protection, the research is carried out: removing and replacing radiation-sensitive components, arranging and installing actuators tightly to improve the space utilization ratio; Based on Monte Carlo method, the relationship between the composition of shielding material and shielding effect is simulated, and the phase change material is introduced to prolong the working time of the actuator. The above measures ensure that the electronic device is at 100 鈩,
