2、目標(biāo)函數(shù)、約束條件和設(shè)計(jì)變量是模糊優(yōu)化設(shè)計(jì)數(shù)學(xué)模型的三要素。而在各類(lèi)機(jī)器中,為了實(shí)現(xiàn)各種復(fù)雜的運(yùn)動(dòng)要求,廣泛應(yīng)用著凸輪機(jī)構(gòu)。近年來(lái),國(guó)內(nèi)外采用優(yōu)化設(shè)計(jì)方法進(jìn)行凸輪機(jī)構(gòu)設(shè)計(jì)已取得較大的進(jìn)展。但以往的工作均未考慮到凸輪機(jī)構(gòu)中有些因素的模糊性,致使難以迅速獲得諸方面皆滿(mǎn)意的方案,考慮到約束條件的模糊性,本文建立了凸輪機(jī)構(gòu)的模糊優(yōu)化數(shù)學(xué)模型,并對(duì)一實(shí)例進(jìn)行了模糊優(yōu)化設(shè)計(jì)。關(guān)鍵詞:凸輪機(jī)構(gòu)模糊優(yōu)化設(shè)計(jì)-58-淮海工學(xué)院二○○七屆本科畢業(yè)設(shè)計(jì)(論文)第-58-頁(yè)共53頁(yè)畢業(yè)設(shè)計(jì)(論文)外文摘要Fuzzyoptimaldesignoncam
