摘　　要：空调外机轴流叶片的设计使得叶片材料越来越轻,越来越薄,这就使得空调外机内部的不稳定流动对叶片的影响大大增加,而以往单单考虑气动或结构因素不能满足实际的需求,必须将气动设计和结构设计相结合。本文通过研究空调外机高速旋转叶片流固耦合,对外机轴流叶片进行了全三维流固耦合数值模拟,分析了流固耦合作用对空调外机叶片的气动设计和结构设计相互作用的影响,有效指导空调外机轴流叶片的实际生产。The design of axial fan on air-conditioning outside units makes the fan material more and more light, more and more thin, which greatly increases the influence of the internal unsteady flow on axial fan. In the past, the factor of aerodynamic or structure is separately considered, which cannot satisfy the practice requirement. It is necessary to combine aerodynamic design and structure design.In this paper, fluid-solid coupling on high speed rotating blade for air-conditioning outside units was researched. Numerical simulation for axial fan on air-conditioning outside units in full three dimension was carried out based on the fluid-solid coupling method. The influence of fluid-solid coupling on the interactions between aerodynamic design and structure design of axial fan on air-conditioning outside units was analyzed, which can guide the actual production of axial fan on air-conditioning outside units effectively.
