摘　　要：针对新型流体推进器,通过对叶片的运动学和流体动力分析,研究了作用在叶片上的面力和体力分布规律并导出了它们的计算公式;基于ANSYS环境,建立了一种直翼叶片的有限元模型,研究了非均匀面力的加载方法,获得了面力分布模型;对叶片应力和变形进行了计算与分析,计算结果揭示了直翼叶片的应力和变形分布规律,为优化叶片的结构和提高其强度、刚度提供了理论指导。The distribution laws of surface force and volume force applied on the blade of a new type of liquid propeller are researched and their calculation formulas are derived by means of kinematic analysis and liquid dynamic of the blade.The loading method of non-uniform surface force is researched based on the ANSYS according to the derived expressions of surface force and a FEM model of the planary blade is established.The results to stress and deformation analysis of the blade using FEM reveal the distribution law of stress and deformation.They can be used as theoretical guidance for optimizing the structure and improving the strength and stiffness of the blade.
