Abstract
In this study, a lightweight wide impeller for large-area surface treatment was designed and structural stability was confirmed based on finite element(FE) analysis. A lightweight bracket FE model was established through topology optimization, and the optimal FE model was selected after structural analysis. The bending deformation FE analysis was performed, and bending deformation was included in the allowable deformation range. In addition, FE modal analysis was performed, and the range of safe speed(RPM) by rotation was suggested. Ultimately, it was confirmed that this analytical technique is effective for design the lightweight wide impeller.
