摘要：

Thin　walled　tube,　a　main　energy　absorption　component,　is　widely　used　in　collision　design　of　different　vehicles,　LSDYNA　is　applied　to　simulate　the　impact　of　regular　polygon　thin　walled　tube　with　different　cross　section,　and　then　the　Fibonacci　search　is　carried　out　to　obtain　a　maximum　solution　of　energy　absorption　about　the　thin　walled　tube.　It　is　investigated　that　regular　hendecagon　section　is　the　best　solution　to　absorb　the　most　energy　under　the　same　compression　quantity.　Therefore,　thin　walled　tube　with　regular　hendecagon　section　is　suggested　to　be　used　in　collision　impact　design　as　energy　absorption　components.
