By using advanced modelling techniques, we used Inventor in order to design all the main parts of our car, and then manufacture them.
Flow Design is an example of CFD software, which simulates fluids like air or water. CFD software is extremely advantageous compared to physical testing due to the virtually non-existant cost and quick development times. We imported our model as an STL file into Flow Design, a software which simulates a virtual wind tunnel. The software then outputted a crucial value called the drag coefficient, which we analysed and compared carefully to other car iterations and concepts. Through mass iteration, we came to a drag coefficient of just 0.12, with 27 iterations in total and five unique concepts.
FEA stands for Finite Element Analysis, and is the analysis of a body's reaction to certain conditions, such as pressure or stress. Our team used this advanced technology in order to simulate stress on our car, to see how it would hold up against the tough racing conditions it will have to endure. Through iteration, we came up with a design that has minimal stress and will get through the races without even a single scratch.
We manufactured the main body of our car using polyurethane and machined it using the CNC Router. This machine has fantastic accuracy with tolerances of just 0.001mm. For our rear and front wings we used 3D Printing, and made them out of Nylon PA12, as well as for our wheels and axles.
