【摘要】：為提高車門的抗柱撞性能,將基于SIMP理論的拓?fù)鋬?yōu)化方法引入車門防撞梁設(shè)計(jì),得到最佳的防撞梁材料分布;選擇合適的截面構(gòu)造防撞梁,得到一種Y形防撞梁結(jié)構(gòu);結(jié)合響應(yīng)面法和NSGA?Ⅱ多目標(biāo)優(yōu)化算法對防撞梁進(jìn)行多目標(biāo)優(yōu)化。相比于初始設(shè)計(jì),優(yōu)化后防撞梁在保證車門剛度滿足法規(guī)要求的前提下,剛性柱的撞擊侵入量減少22.5%,車門抗柱撞性能明顯提高。
[Abstract]:In order to improve the anti-column impact performance of the door, the topology optimization method based on SIMP theory is introduced to the design of the door anti-collision beam, and the optimum material distribution of the anti-collision beam is obtained, and a kind of Y-shaped anti-collision beam structure is obtained by selecting the appropriate section to construct the anti-collision beam. Combined with response surface method and NSGA? 鈪，
