液壓常用密封元件參數(shù)化CAD圖庫設(shè)計

1、機(jī)電工程學(xué)院畢業(yè)設(shè)計說明書設(shè)計題目: 液壓常用密封元件參數(shù)化CAD圖庫設(shè)計 學(xué)生姓名： 學(xué) 號： 專業(yè)班級： 機(jī)制F0706 指導(dǎo)教師： 2011年5月18日畢業(yè)設(shè)計（論文）任務(wù)書1本畢業(yè)設(shè)計（論文）課題應(yīng)達(dá)到的目的：本題目是基于AutoCAD平臺，應(yīng)用AutoLISP等相關(guān)高級語言進(jìn)行應(yīng)用軟件設(shè)計。密封元件是液壓傳動系統(tǒng)中應(yīng)用量很大的輔助元件，其結(jié)構(gòu)較復(fù)雜，品種多。在液壓傳動系統(tǒng)設(shè)計中繪圖工作量較大。本軟件的設(shè)計目的，就是使液壓傳動常用密封元件參數(shù)化，設(shè)計人員只需在程序引導(dǎo)下點(diǎn)選所需密封元件類型、規(guī)格，就可很快繪出相應(yīng)密封元件視圖，從而減輕設(shè)計人員勞動強(qiáng)度，提高設(shè)計效率。通過本設(shè)計可使學(xué)生在

2、分析了解液壓傳動常用密封元件結(jié)構(gòu)和應(yīng)用高級語言進(jìn)行計算機(jī)軟件設(shè)計方面得到較全面的訓(xùn)練。2本畢業(yè)設(shè)計（論文）課題任務(wù)的內(nèi)容和要求（包括原始數(shù)據(jù)、技術(shù)要求、工作要求等）：1技術(shù)要求：在熟悉加工精度統(tǒng)計分析方法、初步具備用高級語言編程的能力的基礎(chǔ)上，設(shè)計液壓常用密封元件參數(shù)化CAD圖庫，軟件設(shè)計要求：（1）所繪制常用液壓密封元件要符合國家標(biāo)準(zhǔn)；（2）能選擇繪制常用液壓密封元件的三視圖；（3）要求人機(jī)交互界面友好，使用檢索方便快捷。2工作要求：（1）收集相關(guān)資料，了解常用液壓密封元件參數(shù)化CAD圖庫軟件發(fā)展現(xiàn)狀；（2）收集與本畢業(yè)設(shè)計相關(guān)的外文資料，翻譯其中一篇；（3）制訂軟件設(shè)計方案，進(jìn)行方案論證，

3、寫出方案論證報告；（4）設(shè)計液壓常用液壓密封元件參數(shù)化CAD圖庫軟件；（5）撰寫畢業(yè)設(shè)計說明書。目次1 緒論12 AutoCAD的二次開發(fā)22.1 AutoCAD 二次開發(fā)的歷史22.2 AutoCAD 二次開發(fā)的現(xiàn)狀22.3 AutoCAD 二次開發(fā)的發(fā)展32.4 AutoCAD 二次開發(fā)工具種類33 CAD參數(shù)化設(shè)計技術(shù)63.1參數(shù)化設(shè)計技術(shù)63.2參數(shù)化設(shè)計的本質(zhì)及意義63.3參數(shù)化設(shè)計在CAD中的應(yīng)用64 液壓密封元件參數(shù)化CAD圖庫系統(tǒng)開發(fā)84.1概述84.2開發(fā)流程94.2.1用DCL編寫用戶對話框界面94.2.2 SLD文件制作104.2.3國標(biāo)數(shù)據(jù)文件制作104.2.4 LIS

5、標(biāo)數(shù)據(jù)文件制作由于在用戶對話框中顯示的國標(biāo)數(shù)據(jù)和內(nèi)部繪圖函數(shù)調(diào)用的數(shù)據(jù)在格式上不同因此把同樣的數(shù)據(jù)分別做成兩份格式不同的文件保存，以遍內(nèi)部函數(shù)調(diào)用如圖4-2-4 4-2-4 繪圖程序調(diào)用的表文件4.2.4 LISP程序設(shè)計圖4-2-5 主程序流程圖4.2.5 自定義并加載局部菜單4.3 程序的運(yùn)行圖4-3-1 自定義菜單圖4-3-2 液壓密封元件參數(shù)化圖庫圖4-3-3 對話框響應(yīng)用戶動作界面圖4-3-4基點(diǎn)輸入提示圖4-3-5 程序繪圖圖4-3-6 動態(tài)定位提示有時用戶可能用戶可能會誤操作。此時，點(diǎn)擊“確定”后會彈出AutoCAD信息對話框，如圖4-3-7所示。圖4-3-7 信息提示4.4液壓

6、常用密封元件參數(shù)化CAD圖庫開發(fā)結(jié)論（1）、優(yōu)點(diǎn)：比較綜合的運(yùn)用了AutoLISP 語言中的賦值（SETQ），極坐標(biāo)求點(diǎn)（POLAR），表的嵌套，選擇集的處理函數(shù)（SSADD）,各種運(yùn)算符（+ - * /），GET族函數(shù)等等。并且綜合調(diào)用了AutoCAD中的畫線（LINE PLINE）、畫弧（ARC）、畫圓（CIRCLE）、鏡像（MIRROR）等命令。（2）、缺點(diǎn)及改進(jìn)方向由于水平實(shí)在有限，加之時間倉促，程序中總會存在這樣或那樣的缺點(diǎn)與不足。主要有：程序中的參數(shù)化程度不夠成熟，程序中的代碼有重復(fù)和多余的部分，不夠簡潔，可讀性有待提高。所以，在今后的改進(jìn)中要增加一些算法，使參數(shù)化程度提高，精簡代
