A Study on the Structure Analysis of Up-Right Vacuum Cleaner Suction Nozzle Cover

UP-RIGHT 형 진공청소기 흡입구 커버의 구조해석

This investigation is the result of a structural analysis by FEM and test to define the deformation mode of the Up-Right type Vacuum-Cleaner's Nozzle-Cover. In FEM analysis, 3 different conditions were considered separately, such as (1) Compressive force by Belt tension, (2) Friction heat between Belt and shaft and (3) Compressive force combined with heat. Throughout FEM analysis it was found that the deformation was caused by heat and it was proved through a simulation test with a real product.
