摘　　要：针对新型流体推进器,提出叶片结构的设计准则,分析叶片结构参数确定的方法。基于ANSYS环境,建立两种叶片(直翼和S型)的有限元模型,分析比较两种结构叶片在质量、迎流面积相同条件下的自由模态。计算结果揭示了直翼和S翼叶片的模态分布规律,为优化叶片结构和进一步分析叶片动力响应奠定了基础。The design criterions of blades for a new kind of fluid propellers, called Half-Revolution Blade Propeller （HRBP）, were proposed and an approach to determination of the structural parameters of two new kinds of blades was described in detail. The FE models of two blades, straight blade and S blade, were established based on ANSYS. The resonance frequencies and mode shapes of two designed blades, which are different in structure but same in mass and fluid applying area, were investigated to reveal the distribution of the dynamic properties of the two blades for optimizing the blade structure and further determining the structural response to an input excitation.
