A Study of Driving Characteristics and Structural Safety of Scaled Model of Variable Pitch Axial Flow Fan Using Finite Element Analysis

The purpose of this study is to verify the kinematic movement of the variable blade mechanism design for a scaled model of a variable pitch axial flow fan with a capacity of 55 kW and to verify structural safety according to the blade setting angle. The design of the variable pitch mechanism was performed using SolidWorks and the kinematic verification of the slider crank movement was performed through Motion Simulation. The structural safety of each component by the impeller and variable pitch mechanism was verified by deriving the maximum stress according to the blade setting angle using Ansys Workbench.
