摘要: 为解决家用轴流风叶在运行过程中存在摆动幅度大,从而引起振动、噪声等影响用户体验的问题,提出一种风叶变形控制方法。以某型号轴流风叶为研究对象,结合流固耦合仿真方法及高速三维成像变形测试法,通过避开主要做功区域,增大叶根的弯度,提高结构的刚度,从而降低叶片变形量,同时保证气动性能差别不大。改进后的风叶最大摆动幅度从1.388 mm下降至1.074 mm,下降幅度为22%;气动性能试验验证了该变形控制方法及对声品质改善的有效性。

Abstract: To better control the swing amplitude of the fan blade driven by large deformation, a blade control method was presented to reduce the deformation and simultaneously meet the aerodynamic performance, with the combination of Fluid-Solid Interaction simulation and high-speed three-dimensional imaging. Firstly, the main working area was analyzed through the fluid simulation. Then, the camber of the blade root was redesigned, which improved the local stiffness to reduce the whole deformation without seriously affecting the performance. Finally, the maximum swing of new structure decreased from 1.388 mm to 1.074 mm, with a decrease of 22%. The aerodynamic performance test result verifies the reliability of the proposed control method and the improvement of sound quality.
