Assignment Brief

Learning Outcome 1: Have a knowledge and understanding of the importance of validating software to ensure that results are realistic;

Learning Outcome 2: Design CAE simulations from a practical engineering problem;

Learning Outcome 3: Use specialist simulation software to solve typical engineering problems;Design and implement a computer program to solve and validate results obtained from specialist simulation software.

Assignment Brief:

This assignment is focused with the static analysis of an F1 Redbull Front Wing. The students should be able to model and programme simulations in order to obtain results as realistic as possible at low computational expense. The students should also be able to validate the results by checking convergence. It involves the use of a commercial FE (Finite Element) package. CATIA Generative Structural Analysis is suggested.

See attached briefing sheet for all the assignment brief details and marking scheme.

Submission Requirements:
- You are expected to submit Powerpoint slides capturing the objectives of the assessment in short video presentation of no more than 10 slides and duration of 3 minutes video. Your face has to be shown throughout the video otherwise there will no marks allocated.
- You should produce a report with a maximum of 20 A4 pages.

AIMS

To reinforce the structure, so that:

1. The maximum displacement measured at any point is smaller than 2 mm with maximum Down- force based on the CFD analysis of your given speed (e.g.116mph) (this is provided separately) and the initial downforce is 3000N.
2. The Von Mises Stress is below the tensile strength,
3. The weight is as little as possible (ideally, the weight should be reduced).
4. Apply successfully the correct structural optimisation technique Account for at least 5 design feasibility constraints.
5. Maximum of 0.5mm of displacement on the bulkhead due to moment coming from the wing.
6. Identify the correct structural optimisation. Need to explain what gains are to be expected from such optimisation.
7. It is expected to account for a minimum of 5 design feasibility constraints and how these may impact the choice of their structural optimisation technique
8. The natural frequency of the wing has to be simulated for each material and presented.

OBJECTIVES

The objective of this assignment is to reinforce the structure while the weight is reduced. You are only allowed to:

1. Change the material 8 times (4 given materials and 4 of your choice) choice of material should be realistic for the application rather than random.

2. Add fillets to reduce stress concentrations.

The best design should be as lightweight as possible and should not affect the practicality of the Wing, ~10Kg.

You need to identify the original mass and stiffness and work your way through so that you have a meaningful set of results to discuss about.
