中文摘要： 对旋风机具有压力系数高、反风性能好、效率较高、总体结构紧凑等优点，在矿山、隧道和船舶等领域的通风换气获得了广泛的应用。然而，伴随长距离送风的出现，对对旋风机设计理论、分析方法提出了更高的要求，需要开展广泛而深入的研究。本项目将电机和风机作为一个整体，通过数值模拟、样机研制和实验，研究对旋风机流场、电机电磁场耦合分析模型及解耦方法，两级叶轮叶片数配合与电动机定转子槽配合的相互影响和匹配关系以及两级对旋叶轮性能与电动机性能匹配问题。掌握对旋风机运行过程中流体、机械、电、磁和力的变化规律和耦合分析方法，准确计算作用在叶轮上的脉动力波、系统惯性和一、二级电机气隙电磁力波。从而进一步探明影响对旋风机整体性能的关键因素，形成对旋风机全新的机电统一设计理论和分析方法。并通过两级对旋叶轮性能与两级电动机性能的"线（点对点）"匹配研究，为高性能对旋风机调速控制和节能控制提供理论依据。

英文摘要： The counter rotating axial flow fan has the features of high pressure coefficient, good anti-wind capability, high efficiency and compact overall structure, and finds the wide use for the ventilation in the fields of mines, tunnels and ships. With the advent of the long-distance ventilation, however, the requirement to the counter rotating axial flow fan in the design theory and analysis method becomes higher and needs further research. By the numerical simulation, prototype development and experiments, with the electric machine and wind machine combined as a whole, the project works on the coupling analysis model and the decoupling method between the flow field of counter rotating axial flow fan and the electro-magnetic field of the electric machine, the interaction and match-up relationship between the number-matching in the two-level impeller blades and the slot-matching in the stator and rotator of the electric machine, the performance-matching between two-level counter rotating impellers and the electric machine. It's very important to have a good command of the variation rules and the coupling analysis methods of the fluid, mechanical, electric, magnetic fields and forces during the operating process of the counter rotating axial flow fan. The pulse force wave on the impeller blades, the system inertia, fi
