Abstract

Recently, automobile market trends have taken a turn towards eco-friendly vehicles in response to environmental regulations framed to encourage carbon-neutral forms of transportation. The biggest challenge to achieve this goal is adequate weight reduction of the frame of the vehicle. To achieve this, car manufacturers have to replace existing steel system frames with aluminum alloy-based frames. In this study, the basic parameters for related analysis were identified based on extensive mechanical tests by considering the use of A6014-T4 material to fabricate automobile parts. In particular, finite element analysis and comparative verification were performed based on the result of a U-bending test.
