本文针对柔性叶片能量转换装置的结构特点,在对四种弯曲变形叶片翼型气动载荷实验研究的基础上,采用参数化建模技术建立四种弯曲变形叶片实体模型,将实验测得的叶片表面压力加载到结构计算的有限元模型上,并以此为载荷对叶片进行气弹稳定性分析,揭示翼型发生变化后,叶片应力变化规律。研究结果表明:在一定的弯曲变形范围内,较大曲率弯曲变形的叶片结构稳定性较好。 In this paper, based on the structural characteristics of the flexible blade energy conversion device, four kinds of bending deformation blade solid models were established by parametric modeling technology based on the experimental study of four kinds of bending deformation blade airfoils. The measured blade surface The pressure is applied to the finite element model of the structural calculation, and the blade is analyzed for the stability of the aeroelasticity. The variation of the blade stress after the change of the airfoil is revealed. The results show that the blade structure with larger curvature is more stable in a certain range of bending deformation.
