Computer aided design of machine elements

ABSTRACT COMPUTER AIDED DESIGN OF MACHINE ELEMENTS DEM I RH AN, Necdet M.S. in Mechanical Engineering Supervisor. Prof. Dr. İ. Hüseyin FİLİZ August 1996, 155 pages In this thesis, a computer aided design (CAD) package for the machine elements is prepared. Shafts, bolts, anti-friction bearings, journal bearings, helical springs, brakes and V-belts are the elements considered in this study. The developed design package has a modular structure. For each of the machine elements specified above, an interactive computer aided design/selection program is written. A database which consists of material properties, design parameters like stress concentration factors, charts, standard values from manufacturer's catalogues, etc., is prepared to ease the design and selection procedure. The modules were combined under a supervisor program. Programs are written in QuickBASIC and colour graphics are sometimes utilised to communicate with the user. The entire system is implemented on an IBM compatible PC. The use of CAD package for each module is illustrated with examples. Key Words: Computer Aided Design, Machine Elements m
