Abstract

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.
