    摘要:

    以航空發(fā)動(dòng)機(jī)渦輪盤鍛件為研究對(duì)象，應(yīng)用響應(yīng)面法（Response Surface Methodology，RSM）和有限元數(shù)值模擬（FEM）對(duì)鍛造過(guò)程預(yù)成形設(shè)計(jì)的多目標(biāo)優(yōu)化問(wèn)題進(jìn)行了研究。首先以模具充填完整和提高鍛件內(nèi)變形均勻性為目標(biāo)，建立了有限元數(shù)值模擬與響應(yīng)面法相結(jié)合的二階分析模型，并對(duì)優(yōu)化結(jié)果進(jìn)行了討論。其次，在原優(yōu)化設(shè)計(jì)的基礎(chǔ)上以降低鍛造過(guò)程的成形載荷為目標(biāo)進(jìn)行了預(yù)成形再設(shè)計(jì)。結(jié)果表明，應(yīng)用響應(yīng)面法可靈活有效的對(duì)難變形材料鍛造預(yù)成形坯料形狀進(jìn)行多目標(biāo)優(yōu)化設(shè)計(jì)。

    Abstract:

    The multi-objective optimization was studied using response surface method (RSM) and FEM simulation for a preform design of aeroengine disk forging. Firstly, taking the deformation homogeneity within forgings and die filling completeness as the objective, a reduced quadratic model was developed through regression analysis and ANOVA (analysis of variance), and then the optimal results are obtained and discussed. Secondly, redesign and optimization were carried out to reduce the deformation load on the basis of the former optimization results. The results show that RSM is an effective and flexible method to realize multi-objective preform optimization design for hard deformed material forging.
