碩士 === 國立臺灣師範大學 === 工業教育學系 === 84 === 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.
