摘　　要：为了提高高速泵的可靠性,利用专业的转子动力学特性分析软件SAMCEF Rotor对高速矿用抢险泵转子系统进行分析,研究转子的动力特性--临界转速及其振型,根据径向轴承参数建模,分别采用一维梁模型,二维傅里叶模型和三维实体模型进行计算比对,得到了各自的坎贝尔图和临界转速及振型。研究表明,三种模型吻合的状态基本一致,设计方案避免了工作转速达到临界转速产生共振现象。根据转子动力学分析软件SAMCEF Rotor分析研究,临界转速的计算方法比较完善,分析结果较为精确,且一维及二维模型求解法对计算机配置要求低,求解耗时短。In order to improve the reliability of high speed pumps,high-speed mine rescue pump rotor system is analyzed by SAMCEF Rotor software.The dynamic characteristics of the rotor,such as critical speeds and vibration models,are calculated and analyzed.Then the Campbell diagrams,critical speeds and vibration models of one-dimensional beam model,the two-dimensional Fourier model and three-dimensional physical model are obtained and analyzed.The results show that the three models are basically consistent,the design avoids producing resonance phenomenon when work speeds reach the critical speeds.Critical speeds calculation method based on SAMCEF Rotor software package are perfect,the results are more accurate.One-dimensional and two-dimensional model solving save time for their low demand of computer configuration.
