Computer-Aided Mechanical Engineering Design
Spring Term 2009
Course Description
This course covers aspects of computer-aided design (CAD), computer-aided engineering (CAE), and computer-aided manufacturing (CAM) for machine elements and products. The CAD component introduces (SolidWorks) and the use of finite-element analysis (FEA) software (COSMOSWorks) to design and optimize sophisticated mechanical components to meet strength and displacement requirements and minimize cost, mass, or complexity. Finite-element analysis builds on theory learned in machine design - designing components to meet static and fatigue requirements - but uses computer-aided analysis, rather than hand calculations to determine stress and displacement. In the CAM component, a variety of manufacturing methods are used, including rapid prototyping, numerically controlled (NC) machining, injection molding, thermoforming, and vacuum casting. We focus on design for manufacturing, rather than on manufacturing processes. As time permits, we may cover additional topics like computational fluid dynamics (CFD) software (COSMOSFloWorks). Integration of the design, analysis, and manufacturing components of the course is accomplished by using CAD/CAE software to design parts and CAM software to fabricate parts. A series of integrated assignments will culminate in a final design project.
