摘　　要：目前国内相关行业对推流器的受力分析研究还处于初始阶段,缺乏较为系统且实用的计算方法。推流器叶片的设计、强度分析和工作效率计算比较复杂,一般需要用专业的CFD及FLUENT6.0软件进行数字模拟及分析,这对于一些中小企业有难度,因此提出一种简单快捷的计算方法可以用于推流器叶片的设计及制造。参照飞机螺旋桨的受力计算方法,对推流器叶片进行受力计算分析并进行优化设计应用。飞机螺旋桨叶片受力计算的方法是把螺旋桨叶片分割成若干段,再用数值解法计算出每段叶片上的作用力。推流器叶轮的工作原理与飞机螺旋桨一样,其叶片可以采用相同的计算方法算出作用力,使用有限元分析对叶片的强度进行校核,可以快速判断叶片是否安全以及如何提高叶片的强度。该方法得出的作用在叶片上的轴向力还可以用来推算流体的速度,从而定量分析推流器叶轮的推流效果,缩短推流器叶片的设计、试制过程,节省人力物力。At present,the force analysis of the domestic industry is still in the initial stage,the lack of a more systematic and practical calculation method.The design,strength analysis and work efficiency calculation of the pusher blade are more complex,generally professional CFD and FLUENT6.0 software should be used for digital simulation and analysis,which is difficult for some small and medium-sized enterprises,so a simple and quick calculation method is proposed which can be used in the design and manufacture of the impeller blade.According to the force calculation method of aircraft propeller,the force analysis and calculation of the propeller blade are carried out and the optimization design is applied.The method of force calculation of aircraft propeller blade is to divide the propeller blade into several sections,and then the force on each section of blade can be calculated by using numerical method.The working principle of the impeller of the thruster is the same as that of the aircraft propeller.The force of the blade can be calculated by using the same calculation method.The strength of the blade can be checked by using the finite element analysis,so as to quickly judge whether the blade is safe and how to improve the strength of the blade.The axial force acting on the blade obtained by this method can also be used to calculate the velocity of the fluid,so as to quantitatively analyze the effect of the impeller of the thruster,shorten the design and trial production process of the thruster blade,and save manpower and material resources.
