摘　　要：核主泵是核电站的关键设备之一,也是反应堆冷却系统的唯一旋转机械设备,其稳定运转对整个反应堆的正常工作至关重要,因此,针对核反应堆主泵开展转子动力学研究,探究主泵转子部件的模态振型、固有频率和支撑系统的刚度阻尼、液膜厚度十分必要。以国内外有关压水堆主泵及液态金属泵的转子动力学研究为重点,围绕压水堆主泵、钠冷快堆主泵、熔盐堆主泵、铅冷快堆主泵4种核主泵类型,从核主泵及其转子部件的结构特点出发,对现阶段主泵导轴承润滑性能和主泵转子结构固有频率、模态分析、临界转速等转子动力学特性的研究进展进行综述和展望,以期对有关核主泵转子动力学特性的计算分析起到一定的借鉴和指导作用。The nuclear main pump is one of the key pieces of equipment of nuclear power plants,but also the only rotating mechanical equipment of the reactor cooling system,its stable operation depends on the normal operation of the entire reactor,therefore,for the study on the rotor dynamics of the nuclear reactor main pump,it is very necessary to investigate modal shape,inherent frequency and rigidness damping of support system and liquid film thickness.With focus on the domestic and international research methods on the rotor dynamics of pressurized water reactor main pumps and liquid metal pumps and based on four types of nuclear main pumps:pressurized water reactor main pumps,sodium-cooled fast reactor main pumps,molten salt reactor main pumps and lead-cooled fast reactor main pumps,the research progress on the lubrication performance of main pump guide bearings and the rotor dynamics characteristics such as the inherent frequency,modal analysis and critical speed of the main pump rotor structure at the present stage was reviewed and prospected starting from the structural characteristics of nuclear main pumps and their rotor components with a view to providing certain reference and guidance for calculation and analysis of rotor dynamics characteristics of the nuclear main pumps.
