基于VC++金屬切削機床主傳動系統(tǒng)優(yōu)化設計（有VC++工程）,基于,vc,金屬,切削,機床,傳動系統(tǒng),優(yōu)化,設計,工程 摘要 優(yōu)化設計是在一定條件（各種設計因素）下所得到的最佳設計值，其內容為將設計問題的實際物理模型抽象為數(shù)學模型，并利用有關計算機軟件對數(shù)學模型進行求解，從而得到最優(yōu)解的過程。最優(yōu)化技術是工程設計的基礎。由于計算機技術的普及應用和運算能力的提高，使得基于計算機的優(yōu)化設計在求解復雜系統(tǒng)的最優(yōu)解方面具有明顯的優(yōu)勢，從而推動了優(yōu)化設計在工程設計上的廣泛應用。優(yōu)化設計的一般步驟為：１.建立系統(tǒng)的數(shù)學模型，一般來說，模型由基本的平衡方程、工程設計關系式以及描述系統(tǒng)內物理現(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系和設計變量對系統(tǒng)性能標準的影響，確定模型的目標函數(shù)；２.找出系統(tǒng)的約束條件，即上述方程的一些補充不等式，用以來確定允許范圍、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。本文通過最低傳動比、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果。 關鍵詞 主傳動系統(tǒng) 優(yōu)化設計 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.
