1. 實驗力學研究室 1 Key Elements of a Successful FEA Implementation

2. 實驗力學研究室 2 Three key factors: 1.A constant evaluation and reevaluation of the process. 2.A well-conceived implementation plan stating the expected benefits and goals. 3.A documented means to verify the results and evaluate the business benefits/measured goals.

3. 實驗力學研究室 3 I.Key Success Factor:Evaluation 1.Corporate needs, both economic and technological. 2.People and computing resources. 3.Current simulation industry offerings.

4. 實驗力學研究室 4 Economic Needs A review of the possible business benefits of simulation: (1)Cost of delay (2) product musts versus product wants.

5. 實驗力學研究室 5 (1)Cost of Delay 1.Product Development Costs 2.Missed Sales 3.Lost Market Share 4.Summarizing Cost of Delay

6. 實驗力學研究室 6 (2)Product Musts versus Product Wants 1.Product Musts “Product musts” refer to components or systems within a design that have historically required iterations to fine tune structural performance. 2.Product Wants are parts that historically have been problem free, including parts successfully used on similar products or parts similar to other successful parts. 3.Summarizing the Economic Benefits of FEA Is the goal to reduce development time or cost? Will the greatest impact derive from cutting material costs? Will market share increase if safer products are developed or quality is improved?

10. 10 Personnel Resources 1.First and foremost is the correct choice of users. The chosen individuals should think the technology is exciting and be willing to devote time to learning theory and practical application techniques. 2.Moreover, the analyst should have a solid background in engineering fundamentals and mechanics of materials with sound engineering judgment so that the problem setup, assumption set, and results interpretation are correct.

11. 實驗力學研究室 11 Project Schedule Resources To get the most out of your investment, resource planning and schedule creation must accommodate up-front simulation on at least the “product musts”. Identify and map out time to properly install, train, execute, and verify the simulation process.

12. 實驗力學研究室 12 1.Evaluating FEA Suppliers 2.Review the minimal capabilities based on the product requirements that your chosen tool should possess. 3.Evaluate suppliers’ market share,installed base,and reputation in the market. Evaluating FEA Systems 1.CAD Compatibility 2.Finite Element Modeling: The Preprocessor 3.Solution Accuracy 4.Support and Training

13. 實驗力學研究室 13 Ⅱ.Key Success Factor : Implementation 1.Your plan 2.The training program 3.Your choice of initial and ongoing projects

14. 實驗力學研究室 14 Implementation Plan Goals or business benefits of the technology. Periodic reevaluation. Process for initiating an analysis or study. Develop documentation procedures. Build time for verification into the plan. Ongoing training and education.

15. 實驗力學研究室 15 Training 1.Internal Training and Coaching Programs 2.External Training and Coaching 3.Choosing a Coach

16. 實驗力學研究室 16 Ⅲ.Key Success Factor: Verification 1.Economic Verification 2.Technical Verification Develop an understanding of the full system, including design tolerances, manufacturing tolerances, and assembly methods. Perform a sanity check on methods and assumptions after the analysis.

17. 實驗力學研究室 17 Assemble a testing program for assumption verification and data correlation which should be performed by or observed by analyst. “Test what you analyze, and analyze what you test” Document your assumption, methods, results, and verification steps.
