DELFT, 12 October 2017 – This morning, the Nuon Solar Team of the Delft University of Technology won the World Solar Challenge in Australia for the seventh time. Thanks to automation of the design process, a completely new concept of the solar car was made. Because of this, Nuna was lighter, faster and more sustainable than ever before.
With the ParaPy software, the team has made thousands of designs for the Nuna in the past half year. By comparing all versions, ultimately a winning design was found.
“With this software we have saved an incredible amount of time in the design process. Never have we been able to analyze so many designs for Nuna. As such, we have been able to make a clear data-driven choice for the most optimal design”, says Steven de Rooij, Technical manager of the Nuon Solar Team.
Because the rules of the competition change every edition, the team is under a large pressure to design and build a new solar car in a very short period of time. Usually this results in only small improvements to parts of the car. This year, with the acceleration enabled by ParaPy, the team could afford to try a fundamental change in shape. Nuna is now much smaller and more efficient, and it even sails with the wind.
Accelerate design processes
More and more companies are running into the limits of humans when it comes to continuously improving their (technical) products. The growing complexity due to an ever-increasing amount of knowledge from different disciplines, leads to designers spending at least 80% of their time on non-creative, routine tasks. This was also applicable to the Nuon Solar Team.
“Take for instance the reduction of the aerodynamic drag of the Nuna (a creative task). For every shape adjustment of the car, the team creates a 3D-model and associated simulation. Next to that, the team needs to verify the strength of the car, the manufacturability and whether the pilot still fits”, explains Reinier van Dijk, CEO of ParaPy. “All this costs a lot of time. Our automation software allows for many more design iterations in the same amount of time. Resulting in a design for the Nuna that is smaller, lighter and more efficient than ever, but also passes all the requirements. We are proud to see that this paid off and that ParaPy helped in making Nuna the fastest car on the track this year.”
