基于VC++金屬切削機(jī)床主傳動(dòng)系統(tǒng)優(yōu)化設(shè)計(jì)（有VC++工程）,基于,vc,金屬,切削,機(jī)床,傳動(dòng)系統(tǒng),優(yōu)化,設(shè)計(jì),工程 摘要 優(yōu)化設(shè)計(jì)是在一定條件（各種設(shè)計(jì)因素）下所得到的最佳設(shè)計(jì)值，其內(nèi)容為將設(shè)計(jì)問(wèn)題的實(shí)際物理模型抽象為數(shù)學(xué)模型，并利用有關(guān)計(jì)算機(jī)軟件對(duì)數(shù)學(xué)模型進(jìn)行求解，從而得到最優(yōu)解的過(guò)程。最優(yōu)化技術(shù)是工程設(shè)計(jì)的基礎(chǔ)。由于計(jì)算機(jī)技術(shù)的普及應(yīng)用和運(yùn)算能力的提高，使得基于計(jì)算機(jī)的優(yōu)化設(shè)計(jì)在求解復(fù)雜系統(tǒng)的最優(yōu)解方面具有明顯的優(yōu)勢(shì)，從而推動(dòng)了優(yōu)化設(shè)計(jì)在工程設(shè)計(jì)上的廣泛應(yīng)用。優(yōu)化設(shè)計(jì)的一般步驟為：１.建立系統(tǒng)的數(shù)學(xué)模型，一般來(lái)說(shuō)，模型由基本的平衡方程、工程設(shè)計(jì)關(guān)系式以及描述系統(tǒng)內(nèi)物理現(xiàn)象的物理特性方程式所組成。該模型描繪了各變量間的相互關(guān)系和設(shè)計(jì)變量對(duì)系統(tǒng)性能標(biāo)準(zhǔn)的影響，確定模型的目標(biāo)函數(shù)；２.找出系統(tǒng)的約束條件，即上述方程的一些補(bǔ)充不等式，用以來(lái)確定允許范圍、最大最小性能要求、或確定系統(tǒng)的邊界條件；３.求出最優(yōu)解。本文通過(guò)最低傳動(dòng)比、模數(shù)、齒數(shù)建立約束條件，最后利用鮑威爾方法得出最佳結(jié)果。 關(guān)鍵詞 主傳動(dòng)系統(tǒng) 優(yōu)化設(shè)計(jì) Abstract optimization design is the optimum design value received under certain terms (various kinds of design factors), whose content is designing from actual physical model of question to a mathematics model, and utilizing relevant computer softwares to solving the mathematics model, and get the optimum course that solves . It is a foundation of engineering design to optimize technology most. Because of the popularization and application of the technology of the computer and improvement of operation ability, optimization design based on computer make the solving in complicated system optimum has obvious advantages, and promoting the wide application in engineering design of optimization design. The general steps of optimization design are following: 1.Setting up systematic mathematics model, generally speaking, the model makes up by the the equation of balance, engineering design relational expression and equation of the physical phenomenon in the system describing the physical characteristic. The model describes the interreaction among every variable and designing the impact on systematic function standard of the variable, confirming the goal function of the model; 2.Finding out the systematic restraint condition , namely some of above-mentioned equations supplements the inequality, with since confirm by range of allowing, not most performance not minimum not heavy ; 3.Working out the most optimum design value. It is through being minimum in this text drive than, modulus, tooth count and setting up terms of restraining, utilizing Powell's method to draw the best result finally.
