알루미늄 센터플로어 터널 부품 개발에 관한 연구

다국어 초록 (Multilingual Abstract)

Aluminum sheet has widely been used in automotive industry to manufacture light-weight vehicles. As the environmental concerns increases, the application of aluminum sheet in automotive body structure is also increases. However, due to the low formability of aluminum, various forming process such as hydroforming, gas blow forming has been introduced to manufacture the body panel part. Although such forming processes can produce the part with fracture-free, the long cycle time has been the limitation for mass production. Therefore, the aluminum sheet has only been used to luxury sedans. In this research, the aluminum center floor tunnel reinforcement has been manufactured by warm press forming which the cycle time is short. To ensure the strength of the part, structural analysis has been done. Also, the forming simulation has been carried out to reduce the try and error for warm forming process.
