Abstract

[[abstract]]本研究旨在以個人電腦為工作平台之AutoCAD R12 for Windows 上發 展平面機構動力分析軟體。軟體規劃為前處理、計算分析及後處理三大模 組。開發工具係使用Autodesk公司提供Third Party 廠商發展應用程式的 介面ADS (AutoCAD Development System)來撰寫計算分析模組、以 AutoLISP 撰寫前、後處理程式,前處理並藉ASI(AutoCADSQL Interface) 函式庫介面以SQL與資料庫溝通。使用者操作介面則以AutoCAD 所提供之 DCL(Dialogue Control Language)模組來設計對話框,並以AutoLISP撰寫 操控對話框之程式。 本軟體之前處理提供具有 圖形預視功能之參數化機構桿件建構環境及輔助操作訊息之功能,以協助 使用者迅速完成機構之建立。計算分析模組負責讀取機構定義資料、圖元 資料,自動產生機構分析所需之統御方程式,並進行數值計算及動態模擬 並將計算結果儲存。後處理則呈現分析結果。 經實例驗證結果顯示,本軟體除了可供一般平面機構動力分析之用,由於 提供極佳的前處理輔助操作訊息之功能,亦適於輔助機動學教學之用。 關鍵詞:平面機構、動力分析、電腦輔助設計、AutoCAD。 The purpose of this research was mainly to develop a software of dynamics analysis for planar mechanism using the AutoCAD R12 for windows. The structure of the software is divided into three parts including pre- processor module, analysis module and post-processor module. The developing tools offered by Autodesk for third party partner are used to develop application programming interface. The dynamic analysis program was implemented using AutoCAD Development System (ADS). AutoLISP pogramming language was used to create pre-processor and post-processor program codes. ASI was used to communicate the database by SQL. The Graphical User Interface is implemented using Dialogue Control Language (DCL) to create the dialog box drivern by AutoLISP programs. For helping the user to construct the mechanism effectively, the pre-processor offers a graphical preview function and assistant operation message for linkage design. The analysis module reads input data, generates and sloves governing equations. It then showed the animation of the mechanism and saves the results. The post-processor presents the analysis results. Results of the research showed that this software is not only suitable for dynamic analysis for planar mechanisms, but also for instructional purposes in mechanism. Keywords:Planar mechanism, Dynamics analysis, Computer Aided Design, AutoCAD The purpose of this research was mainly to develop a
