【摘要】：电机作为机器人控制和传动系统的核心部件,其在核灾变环境下的稳定运行对机器人的寿命起到决定性作用。提高用于核环境作业机器人的电机耐辐射等级,对于研制核电站紧急救灾机器人具有十分重要的意义。采用傅里叶红外光谱(FTIR)、力学性能测试等对于不同结构聚酰亚胺(PI)绝缘纸的综合性能进行对比分析,发现使用柔性单体制备的PI绝缘纸,其综合性能最佳,在100 Mradγ射线辐照后性能无明显降低。结合FTIR和扫描电镜测试,分析了商用复合锂基润滑脂在γ射线辐照下结构性能的变化。最后对国产普通电机中耐辐射性能较差的绝缘系统、润滑系统等部件的改进替换,成功制备了耐受γ射线辐照总剂量高于100 Mrad的耐辐射直流电机。该通用材料和技术对于开发耐核辐射机器人用伺服电机等具有普适性。
[Abstract]:As the core component of robot control and transmission system, the stable operation of motor in nuclear catastrophe environment plays a decisive role in the life of robot.It is of great significance to improve the radiation resistance of the motor used in the nuclear environment working robot for the development of the nuclear power plant emergency relief robot.The comprehensive properties of polyimide (Pi) insulator paper with different structures were compared and analyzed by Fourier transform infrared spectroscopy (FTIR) and mechanical property test. It was found that Pi insulator paper prepared with flexible monomer had the best comprehensive performance.There was no significant decrease in the properties after irradiation with 100 Mrad 纬 -rays.The changes of structure and properties of commercial lithium-base grease irradiated by 纬 -ray were analyzed by FTIR and SEM.Finally, the radiation-resistant DC motor with a total dose of more than 100 Mrad of 纬 -ray irradiation was successfully prepared by the improvement and replacement of the insulation system and lubricating system with poor radiation-resistant performance in the domestic ordinary motor.This universal material and technology is universal for the development of nuclear radiation-resistant robot servo motor.
