【正文】 本科畢業(yè)論文（設(shè)計）論文題目：基于 鏈傳動的優(yōu)化設(shè)計與編程學(xué)生姓名：所在院系： 機電學(xué)院所學(xué)專業(yè)： 機械設(shè)計制造及其自動化導(dǎo)師姓名： 完成時間：摘要 鏈傳動被廣泛應(yīng)用于動力傳遞中，幾乎所以的車輛和機床，還有其它機械均應(yīng)用了鏈傳動傳動裝置。因此，對鏈傳動的設(shè)計是十分重要和必要的。 這篇文章主要介紹了運用優(yōu)化設(shè)計對鏈傳動進行設(shè)計的一般方法和具體過程，優(yōu)化設(shè)計是 20 世紀(jì) 60 年代發(fā)展起來的一門新學(xué)科，它是基于計算機技術(shù)的一種相當(dāng)有效的、能尋找出最優(yōu)結(jié)果的設(shè)計方法。該設(shè)計仍然運用了傳統(tǒng)的機械設(shè)計方法，但是它又不同于傳統(tǒng)的設(shè)計方法，它采用了名為 visual basic 的軟件，該軟件能極大地提高工作效率和設(shè)計精度，并能很大程度地減少工作時間。關(guān)鍵詞 鏈傳動，visual basic，設(shè)計 AbstractThe chain trasmission are widely used for power transmission, almost all the vehicles and machine tools and other machines employ the chain transmission drive. so the design of chain transmission drive is very important and necessary.The article mainly introduce the method and the detailed process of the designing of the chain transmission drive by using Optimal Design which is a new subject developed from the 1960s,and it is a fairly good way to search for the best result of the design based on the puter technology. The design still use the traditional means of machinery design, but it is very different from the traditional means, because it also adopt a soft ware named Visual Basic ,which can greatly improve the work efficiency and accuracy and cut short the work time.Keywords chain transmission 。 visual basic 。 design目錄1 緒論 ...............................................................................................................52 設(shè)計要求 ........................................................................................................63 鏈傳動簡況及本課題的研究意義 ....................................................................6 鏈傳動的分類及傳動特點 .........................................................................6 主要研究內(nèi)容 .......................................................................................74 鏈輪的常用材料的分析 ..................................................................................95 鏈傳動各個參數(shù)的分析 ..................................................................................9 鏈輪的齒形 .............................................................................................9 節(jié)距 .................................................................................................10 主動鏈輪的齒數(shù) 和從動輪齒數(shù) ......................................................131z2z 傳動比 I ................................................................................................13 中心距 A.................................................................................................13 鏈的節(jié)距 P 和鏈節(jié)數(shù) LP .........................................................................13 計算當(dāng)量的單排鏈的計算功率 ................................................................16 當(dāng)量功率 .........................................................................................16 鏈速計算 ................................................................................................17 鏈傳動過程中的力 ................................................................................186 鏈傳動優(yōu)化設(shè)計的數(shù)學(xué)模型 .........................................................................19 目標(biāo)函數(shù)的確定 .....................................................................................19 鏈傳動中設(shè)計變量的確定 .......................................................................19 鏈傳動設(shè)計中約束條件的確定 ................................................................19 主動輪齒數(shù) Z1 約束 .............................................................................19 節(jié)距 p 與中心距 a 比值約束 ..........................................................19 鏈速 v 的約束 .................................................................................19 鏈輪中心距 a 的約束 .......................................................................20 鏈節(jié)數(shù) Lp 的約束 .............................................................................20 鏈板疲勞強度限定的額定功率 的約束 ........................................200?p 鏈條靜強度 s 約束 ...........................................................................20 設(shè)計過程 ................................................................................................20(1) 設(shè)計變量： ............................................................................................20 鏈傳動設(shè)計的優(yōu)化方法與結(jié)果 ................................................................217 鏈傳動的優(yōu)化設(shè)計的方法 .............................................................................21 編程語言的選擇 .....................................................................................21 關(guān)于 VISUAL BASIC..................................................................................22 VISUAL BASIC 的其它特性 ........................................................................22 程序運行界 ......................................................................
