1. Design event presentation
Queen Mary, Formula
Student

2. Design goals
 Simplicity
 Reliable
 Easy to maintain
 Complete endurance and dynamic
events

3. Chassis
 Why space-frame and not a monocoque?
 Load path visualization is easier
 Easy to construct
 Cheaper

4. Load path
 Load path in suspension
Front wheel brake torque
Node to node connection
 Loads are only in tension and compression
 Triangulations added at all 4 nodes

5. Effectiveness
For the same load of 5000 N, constraints and material

6. Cockpit
 Driver to seat at a node
junction
 Wider cockpit than
required template
 Extra safety against side
crash
 Ease of Driver
accesibility

7. Cockpit
 Extra rail of tube connected to shoulder
harness bar
 Tremendous brake forces needs a
simple load path

8. Material selection
Chromoly 4130 CDS Mild Steel
 Chromoly requires heat
treatment
 Mild steel is easier to weld
 No crucial performance gain
from using Chromoly
 Mild steel is cheaper

9. Tube dimension
 Increasing wall thickness adds little
to moment of inertia but more to
weight
 Increasing O.D. adds a lot to
moment of inertia but little to weight
 Original choice was from FSAE
minimum dimensions

10. Fuel Tank
 Fuel tank designed for 4.5 L capacity
 Sight tube and steel plug located on sides
 Composed of Aluminium plates
 Fuel tank will be mounted behind the seat

11. Intake Manifold
 Tuned for pressurized wave induction at 10000 rpm
 Relatively small plenum
 Manufacturing will be done by 3D Printing
 CFD simulation displayed good flow of air
