[구조강도] 에너지 흡수용 Honeycomb Core 설계에 관한 연구 = A Study on the Design of Energy Absorbing Honeycomb Core

다국어 초록 (Multilingual Abstract)

Honeycomb has the unique property of crushing in a uniform, predictable and efficient manner. This makes it well adapted for energy absorption applications. Its property is mainly depending on cell configuration. Honeycomb cell configuration was designed by satic crush strength test. In this study we developed the honeycomb cell configuration optimization system consisted of mesh generator optimiaztion routine and Finite Element Solver. Mesh generation programs are employed for generate arbitrary cell configuration and apply complicated boundary and loading condition automatically. BFS(Broyded-Fletcher-Shanno) method is used to optimize the cell configuration. Correlation between test and finite element simulation is conducted about energy absorbing batter of regulation FMVSS 214. And, using optimization system. honeycomb cell size is detected with an arbitrary strength
