摘　　要：自主设计搭建了对旋轴流风机叶轮系统流固耦合实验台。对设计工况和非设计工况下风机内部流固耦合流动进行了深入的实验研究,并运用信号分析方法进行了信号分析和数据处理。揭示了二级叶轮轴向振动与级间流场压力脉动之间的流固耦合作用,为进行故障诊断和失效机理分析奠定了基础。Design and build voluntarily the experimental facilities of the fluid-solid coupling of the impeller system in the disrotatory axial-）flow fan. The coupling flow experiment in the axial-flow fan is studied deeply under designed and off-designed conditions, the signals are analyzed and the data is dealt with by signal analysis. The study reveals the fluid-solid coupling between the secondary-impeller axial vibration and the intervalve pressure pulsation, and provides the basis for the fault diagnosis and the invalidation mechanism analysis.
