Static Analysis and Optimization of Axial Flow Rotor Hub of Fan

The axial flow fan is the main selected model of the mining main fan for its compact structure, moderate flow and pressure head. In order to further explore the possible optimization path of the fan, in this paper, taking the rotor and hub of the axial flow fan as the research object, the statics characteristics and the possible energy-saving path of the rotor and hub are analyzed. Through the finite element analysis and numerical calculation, the feasibility of optimizing the hollow area of rotor and hub is determined, and the porous material welding method is used to optimize. The results show that the energy consumption of the optimized rotor and hub hollow area is significantly reduced, indicating that the research work has achieved initial success.
