摘　　要：针对国内外文献中所分析的离心泵转子振动的影响因素,结合试验所得结果对离心泵的计算模型、计算设计方法和振动故障等研究现状进行综合分析,提出离心泵转子振动分析应在已有的分析理论基础上分别分析离心泵的汽蚀、流体激振、密封间隙力等因素对离心泵转子振动的影响,并提出将流固耦合、汽蚀和碰摩耦合理论综合起来分析离心泵转子部件的振动现象。For the analysis of domestic and foreign literature in the centrifugal rotor vibration factors,combined with the experimental results of the calculation of the centrifugal pump model,the design fault,etc.and vibration research comprehensive analysis,vibration analysis of the centrifugal rotor should be analysis has been obtained based on the theory of the centrifugal pump cavitation,respectively,fluid vibration,seal gap centrifugal force and other factors on the rotor vibration,and the proposed fluid-structure interaction,cavitation and rubbing combination of centrifugal pump theory the phenomenon of rotor vibration components.
