Optimization of Crash Box Based on Car′s 40%ODB Crash
摘要
Abstract
A submodel which can simPlify the whole vehicle 40%ODB( Offset Deformable Barrier) crash is established by LS-DYNA. The reliability of the submodel is analyzed. The structure of crash box is oPtimized based on the submodel. Results show that:the energy absorbed by crash box is in-creased by 56 . 8%;the Peak secforce of crash box is reduced by 19 . 3%.关键词
