Sammanfattning
In the realm of the automotive industry, the development of vehicles entails the
fulfillment of numerous requirements such as appealing design, comfort, safety, and
efficiency. Notably, in recent years, the significance of efficiency has grown due
to mounting environmental concerns regarding internal combustion engine (ICE)
vehicles and limitations on the range of battery electric vehicles (BEVs).
Of the various engineering aspects, aerodynamics assumes a pivotal role in determining
the performance of cars, exerting a substantial influence on vehicle efficiency.
To investigate and enhance aerodynamics, automotive companies adopt a combined
approach involving both digital and real-world testing. The former is accomplished
through the utilization of Computed Fluid Dynamic (CFD) analyses, while the latter
entails wind tunnel testing of clay car models.
This thesis covers the current approach to the study of aerodynamics, focusing on
the issues that characterize the existing workflow, including downtime and inaccuracies.
In response to these challenges, a novel workflow founded on automated
mechatronics optimization is introduced and a prototype is tested, thereby showcasing
a fresh and more efficient modality of working with clay car models within
wind tunnel facilities.
The proposed workflow aims to enhance the aerodynamic optimization of vehicles by
implementing a scalable, plug-and-play system that expedites the process and yields
advanced, efficient designs. This endeavor has brought to remarkable results, such
as the development of an innovative diffuser configuration that enhances efficiency
during side-wind conditions, as well as a 73.4% reduction in time within the current
wind tunnel workflow through the application of automated mechatronics.
