The purpose of this paper is to prove the importance of analysis conditions on FEA of axial buckling. Moreover, optimization design for crashworthiness members was carried out to improve the crashworthiness by considering forming history. As the results, it is important to consider the forming history in order to estimate the crush characteristics accurately on any type analyses. Furthermore, the results of optimization design showed that the optimized side member considering forming history could get better optimal solution than the optimized side member unconsidering forming history.軸圧縮衝撃負荷を受けるハイドロフォーミング部材の衝撃エネルギー吸収特性を評価するシミュレーション技術の精度を向上するために，部材成型プロセスの加工履歴の影響を評価する手法を確立した．
