Assignment Brief:
This assignment is focused with the static analysis of an F 1 Red bull 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.

INTRODUCTION:
You will use a commercial FE package to perform an analysis on a Red bull F 1 Front Wing subjected to high compression values. It is suggested that you use the Generative Structural Analysis environment from CATIA
V 5 and use of a software different than CATIA is unsupported, thus not recommended.

This assignment is based on a real engineering problem and we hope you enjoy it!

MODEL

Figure 1 shows the CATIA 3D CAD model of a loaded component to be studied which can be found as part of the tutorials. Please note the file is 1:10 and for analysis you need to work on real size.

Figure 1 â€“ CATIA 3 D CAD model of the Red bull Front Wing

This part is made from steel and needs to be remodelled in such way that while the overall shape remains intact certain areas are reinforced to take the maximum load.

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.116 mph)
2.The Von Mises Stress is below the tensile strength,
3.The weight is as little as possible (ideally, the weight should be reduced).

OBJECTIVES:
The objective of this assignment is to reinforce the structure while, at the same time, weight is reduced. You are only allowed to:

1.Change the material 5 times (three given materials and two of your choice)
2.Add ribs/reinforcements at the most convenient locations with the lightest geometry possible,
3.Add fillets to reduce stress concentrations.

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

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.

REPORT LAYOUT
Only the authorsâ€™ numbers (SRN) should be shown.

THE REPORT SHOULD NOT EXCEED A TOTAL OF 10 PAGES.

It must be submitted in a word document. Alternative formats will not be accepted.

You must deliver the CATIA files of your final model by uploading it on Canvas. Failure to do so may result in no marks being awarded.

Presentation is a very important aspect of your report, mostly because of clarity. Use page numbers, headings, figure/table captions and numbers (and always refer to them in the text), etc.

Above all, the report should look like a proper professional technical document.

DELIVERABLES, OBJECTIVES AND MARKING SCHEME.
The marking scheme (and, therefore, the recommended layout) is presented below. Always provide evidence (justification, by means of calculations, print screens 1, diagrams, etc).

• Print screens of CATIA are recommended to be made using a white background.
• Generate the initial model, showing:

a. Element size and Absolute Sag Values
b. Constraints, and exactly where they are applied;
c. Loads, and exactly where they are applied.

• Check mesh convergence with a few (minimum of 5) simulations by changing mesh size

a. A graph of the maximum displacement vs the number of elements (or mesh size);
b. A graph of the maximum Von Mises Stress vs the number of elements (or mesh size);
d. A picture of the final Von Mises stress distribution, highlighting the most
problematic locations;
e. A picture of the final deformation, highlighting the most problematic locations.

• Optimise the model by changing material, adding reinforcements/ribs and/or adding fillets so that the aims are achieved.

a. A picture of the meshed and optimised model, describing the reasons for the different options and solutions;
b. A picture of the Von Mises stress distribution on the optimised model, highlighting the locations where visible improvements were found;
c. A picture of the vector deformation along the part on the optimised model, highlighting the occasions where visible improvements were found;
d. Comment on the Von Mises stress distribution and deformation of the optimised model, comparing these values to the ones obtained in the original model.

NB: If the only change made is in the thickness without any other visible effort, your model will be marked with zero marks.

NB: Due to the nature of this assignment, it is very unlikely (not to say impossible) that different groups of students come up with the same solution. Please take this as an advice on how to avoid being charged for academic misconduct. We take it very seriously, so please make sure that what you present is your own work.
