Measuring Drag and Visualizing Flow Patters Around a Vehicle
Goal: Test a car in a wind tunnel at max speed of 40 m/s and compare to another (provided by professor) for drag measurement and perform visualization of the flow patterns around the vehicle.
Group Project: 4 Members
Materials Provided: Wheels, Axles
As a group, we had to design and build our car from the given specifications below:
Axles must be free to rotate
Min. ground clearance: 10mm
Walls must be solid
Max. vehicle weight: 50 grams
Min. Load capacity: 1000 grams (to be loaded in the middle, top section of vehicle)
Connector for wind tunnel (Max. diameter 1.5mm)
Weight was an issue so we made it as thin as possible
Stress test with a load of 1000 grams
Mesh generated for simulation
Stress test results – Displacement plot. 0.006 max.

There are many more details to this project that I am excluding for brevity. We worked on different models, built by different team members and did several iterations. The model above is the one I worked on and kept refining as the last product to turn in. This project was a great learning experience. I’m sure learning more about Solidworks for design and simulation will come in handy in many future projects.
Big thanks to everyone in the group for working hard to get this done and learn a lot. Also, our great TA who was always ready to answer our many questions.
