An optimization process of a thin - walled structure was performed by the response surface method , which took the maximum absorption energy from an impacting process as objective , the properties of the thin - walled structure as variables , and the impacting axial force as constraint 摘要運用響應面法,以碰撞吸收能量最大為目標,薄壁結構幾何尺寸為設計變量,碰撞作用力為約束,對薄壁結構進行結構優化。
