【摘要】：采用多級(jí)優(yōu)化方法對(duì)碳纖維增強(qiáng)復(fù)合材料加固中心孔鋼板進(jìn)行優(yōu)化設(shè)計(jì),首先,采用拉丁超立方方法選取試驗(yàn)樣本點(diǎn),利用移動(dòng)最小二乘法擬合近似代理模型,在代理模型基礎(chǔ)上采用自適應(yīng)響應(yīng)面優(yōu)化方法優(yōu)化基本鋪層厚度;然后,結(jié)合復(fù)合材料制造約束條件,利用Optistruct對(duì)鋪層順序進(jìn)行優(yōu)化,得到最佳鋪層設(shè)計(jì)方案。經(jīng)過多級(jí)優(yōu)化設(shè)計(jì)后,鋼板中心孔處應(yīng)力分布更合理,最大Mises應(yīng)力減小了56.6%。
[Abstract]:The multi-stage optimization method is used to optimize the design of the steel plate strengthened by CFRP. Firstly, the Latin hypercube method is used to select the test sample points, and the moving least square method is used to fit the approximate agent model. Based on the agent model, the adaptive response surface optimization method is used to optimize the basic layer thickness, and then the optimal layering design scheme is obtained by using Optistruct to optimize the layering sequence in combination with the composite manufacturing constraints. After multistage optimization design, the stress distribution at the center hole of steel plate is more reasonable, and the maximum Mises stress is reduced by 56.6%.
