Design of Moving Blade and Calculation of Centrifugal Force Based on Axial-flow Fan Used in Mine

During the design of an axial flow fan used in mine,the reasonable design of the moving blade and the calculation of the strength are needed.The calculation of the centrifugal force of the moving blade has been finished,because the centrifugal force from the rotating of the moving blade is the primary force.The method above can improve the dependability of the design,and has important value of engineering applications.
