Our Chassis Design 

2019

Authors: Haydn Scott-Kilsby & Jack Chilton 

To uphold QUT Motorsport’s promise to pushing the limits of race car design and development, the chassis was constructed by building on the techniques first used by the team in QEV1. Central to this was the decision to use aluminium honeycomb as the primary chassis material. The honeycomb offers exceptional material strength compared to the traditional space-frame approach, without requiring a heavier and less workable replacement. The shape itself received dozens of variations, simulations, test and updates before it reached the manufacturing stage. All of this was done to ensure that every crease, panel and hole was perfectly placed to unite the efforts of the numerous teams working in harmony to develop the car from the ground up and push the envelope further.

The most important focal point for the team was driver safety amidst the various areas of cutting-edge development. The team’s decision to use honeycomb allowed the driver compartment to have far stronger penetrative resistance than the traditional spaceframe. In addition, thicker panels and carbon wrapping allow the driver to be further protected from potential injury. While this costs some additional weight, it’s a vital platform that future iterations of the team will be able to build upon throughout the next few years. Manufacturing the chassis on-campus also offered the team an opportunity to engage with practical learning in a way that is difficult to offer through standard coursework. The new chassis allows QUT Motorsport to aggressively pursue ambitious development within an environment safe enough to do so.
