VP in Engineering • Virtual Prototyping (VP) – Simulation-Based Design (SBD) – has gained popularity in most engineering design processes. • Significant demand from industry for students trained in this methodology. • However, not much room in engineering curriculum permits widespread adoption in the lecture-based classroom currently. http://www.dynamicdesignermotion.com/
Tutorials Goal • Introduce VP to students in Machines and Mechanism Design • Develop a series of Web-Based Self-Paced Tutorials, permit the students to: • Create engineering analysis models • Develop skills for interactive SBD • Develop engineering judgment http://www.eng.buffalo.edu/Courses/mae412/tutorials/index.html
Criteria met? Conventional Approach $$$ 1. Conceptual Design 2. Build Physical Prototype 3. Measure Performance and Test No 4. Modify Physical Prototype Yes 5. Manufacture Product

Why VP now? • The availability of low-cost PC based parametric simulation and analysis tools. • The capability of integrating multiple functionalities into a unified environment. http://www.dynamicdesignermotion.com/
Need for Our Tutorials • Our students do not have experience with • Operating the CAD application software • Analyzing the resulting output • Factors impeding wide-spread adoption of existing tutorials to directly augment the engineering class: • The vendors’ tutorials may be targeted at more experienced user. • The overall complexity and time required to learn these tools. • Lack of linkage (to the course material)
Traditional Approach • Concepts and ideas of mechanism theory are delivered in class-room based lecture. • Mathematical formulation are emphasized. • Approach limits the complexity of the model handled.
VP Approach VP allows us to: • Quantitatively analyze complex mechanisms and their motions. • Interactively examine many different alternatives • Interactively animate motions of the mechanism Grashof Non-Grashof However, is a “black box” approach
