multivariate optimization中文什么意思
例句與用法
- compared with a delta wing aircraft, the double-delta wing configuration has better aerodynamic performance at high angles of attack . an operational analysis was introduced as a method for evaluating training effectiveness of trainer aircraft . approaches to the engineering estimation of aerodynamic characteristics for aircraft with a double-delta wing configuration were studied, and the procedures for determining aircraft performance indices formulated . taking training effectiveness as the objective function and geometric parameters of the wing platform as design variables, through a numerical multivariate optimization arithmetic, the conceptual design optimization for a certain fighter trainer aircraft with double-delta wing configuration was carried out under the constraints of tactical and technical requirements and interrelated geometry . agreement of a calculation example with engineering practice indicates that the optimal design has higher training effectiveness than the baseline design, and in addition, improves the structural force-bearing conditions
雙三角翼氣動(dòng)布局比三角翼飛機(jī)具有更好的大攻角空氣動(dòng)力特性.引入了評(píng)估教練機(jī)訓(xùn)練效能的作戰(zhàn)分析法,研究了雙三角機(jī)翼布局飛機(jī)空氣動(dòng)力特性的工程計(jì)算途徑以及飛機(jī)性能指標(biāo)的確定方法.以訓(xùn)練效能作為目標(biāo)函數(shù)并選取機(jī)翼平面形狀的幾何參數(shù)為設(shè)計(jì)變量,采用多變量數(shù)值尋優(yōu)方法,在戰(zhàn)術(shù)技術(shù)指標(biāo)及相關(guān)幾何約束條件下,對(duì)某高級(jí)教練機(jī)的雙三角機(jī)翼氣動(dòng)布局方案進(jìn)行了優(yōu)化選擇.算例表明最優(yōu)方案不僅比原準(zhǔn)方案具有更高的訓(xùn)練效能,還改善了結(jié)構(gòu)的受力情況,與工程實(shí)踐吻合
