차량용 공조시스템에서 중량저감을 위하여 1.2t 두께를 갖는 AHS 개발

다국어 초록 (Multilingual Abstract)

The development trend of vehicles has increasingly been focusing on reducing fuel consumption and emissions. Recent automotive industry has big challenge to improve the fuel economy and to meet the GHG (Green House Gas) regulations. The GHG regulations required to reduce emission about 30% by next 10 years. To meet the regulations, one of the solution is weight down in the vehicle components not only chassis parts but also cabin parts. So, development of 1.2 thickness thin AHS (Air Handling System) case to meet those requirements was tried. First we experienced in proto tooling base on the CAE analysis. The 3D AHS CAD modeling was designed considering stiffness and stress analysis by CAE, which is using mold flow program. After then AHS mold for mass production was developed with optimized gate, rib thickness, draft angle, and shape of surface. Finally, 1.2 thickness AHS case was developed successfully and meet to engineering specification and design criteria. In addition, tooling technologies and CAE analysis for 1.2 thickness AHS case was set-up.
