자동차 압축기용 마그네슘 합금 EL-cover 성형 공정 설계

다국어 초록 (Multilingual Abstract)

Recently, the industrial applications of magnesium alloy have been increased because it is the lightest structural metal on Earth and has many advantages such as a high specific strength, excellent machinability, high electrical and thermal conductivity, etc. The efforts of the automobile industry to reduce fuel consumption by using lightweight structural materials have accelerated the development of magnesium alloy sheet forming technologies. In this work, in order to apply magnesium alloy to high-performance air-conditioning system for electric vehicles, three cases of multi-stage drawing processes for fabrication of the EL-cover part were designed and the forming failure for each case was investigated by the FEM combined with a ductile fracture criterion.
