Goals:

This course is to prepare seniors in mechanical engineering to develop CAD technology towards solving design problems. In particular, emphasis is placed on developing solid models, finite element analysis, custom design of CAD software to fulfill a particular requirement, development of library of design components and automation. The students are exposed to two major softwares PATRAN and IDEAS.

Prerequisites by Topic:

1. Computational Analysis
2. Design of Mechanical Components

Topics:

1. Course overview, introduction to UNIX and e-mail (1 class)
2. Solid modeling using PATRAN, 2-D and 3-D geometric design (2 classes)
3. Finite element analysis (FEA), model preparation, submitting to FEA, displaying results, automation techniques (2 classes)
4. Solid modeling concepts using IDEAS (2 classes)
5. Variational and Feature Based design modeling, automation techniques ( 1 class)
6. Assemblies, mechanism and mechanism analysis and design (3 classes)
7. Generating drawings from 3-D models, automation techniques (1 class)
8. How to give a good presentation: outlining, use of overhead projectors and other visual aids, presenting as a team.

Computer usage:

Students are scheduled for four (4) 80 minute periods. Four (4) on-line quizzes are given. Approx. eight (8) assignments are given.

Design Project:

Group Design projects are assigned to groups of 3 or 4 students. The progress report is due in the eight week of the class. Students must show relevance of their projects through showing: implementation of design automation code, correspondence with industry or faculty, or work related to an engineering design competition. The design projects are such that they can not be performed manually.
