Analysis of Buckling Behavior of Aluminum Structures for Crash Absorbing 2004-01-1614
Recently, it was required that the body should be made lightweight. The use of extrusion aluminum elements as the body frame structure is one way of satisfying the requirement. In this research, the cross-section was designed to optimum shape for the maximum crash energy absorption. The energy absorption is performed by the plastic buckling deformation. Therefore, the compressive load and an effective deformation was elucidated from the analytical consideration and experiment. The cross-section which is able to absorb greater crash energy was discussed by considering buckling mechanism, and it was verified by the experiment.
