VP in Engineering n n n 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/ 2
Tutorials Goal n n Introduce VP to students in Machines and Mechanism Design Develop a series of Web-Based Self. Paced Tutorials, permit the students to: n n n Create engineering analysis models Develop skills for interactive SBD Develop engineering judgment http: //www. eng. buffalo. edu/Courses/mae 412/tutorials/index. html 3
Conventional Approach $$$ 1. Conceptual Design 2. Build Physical Prototype 3. Measure Performance and Test Criteria met? No 4. Modify Physical Prototype Yes 5. Manufacture Product 4
Virtual Prototyping Less $ !!! 1. Conceptual Design 2. Build Virtual Prototype 3. Measure Performance and Test by Simulation Criteria met? No 4. Refine Virtual Prototype Yes 5. Build Physical Prototype 6. Test Physically Criteria met? No Yes 7. Manufacture Product 5
Why VP now? n n 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/ 6
Need for Our Tutorials n Our students do not have experience with n n n Operating the CAD application software Analyzing the resulting output Factors impeding wide-spread adoption of existing tutorials to directly augment the engineering class: n n n 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) 7
Traditional Approach n n n 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. 8
VP Approach VP allows us to: n Quantitatively analyze complex mechanisms and their motions. n Grashof n Interactively animate motions of the mechanism Non-Grashof Interactively examine many different alternatives However, is a “black box” approach 9
Our Philosophy Link Traditional Approach and VP Approach Link Grashof Traditional Approach Non-Grashof VP Approach 10
Implementation Get familiarized to the tools Phase 1 Understand various mechanisms Phase 2 Develop engineering judgment skills Introduce VP into engineering design process Phase 3 Build physical systems based on SBD 11
