摘　　要：介绍了中国实验快堆一回路钠循环泵转动模型分析与振动特性试验。通过建立钠泵轴系统的转动模型,进行了临界转速的理论分析,并结合对泵工作轴承处和电机轴承处双振幅与均方根振动速度的测量实验,结果表明一回路钠循环泵的振动特性满足运行限值要求。The article introduces the rotational model analysis and the vibration test of the primary sodium pump of China Experimental Fast Reactor. Through the establishment of the rotation of the shaft system model, the critical speed has been analyzed. Combined with the pump bearings and motor bearings at double amplitude and RMS vibration velocity measurement experiment, the results show that the vibration characteristics of the primary sodium pump meet the requirements of the operational limits.
