Dr Cor-Jacques Kat and Mr Arslan Mahmood from the Vehicle Dynamics Group at the University of Pretoria, South Africa recently completed a one-month secondment to Dr Barys Shyrokau at the Section of Intelligent Vehicles, Department of Cognitive Robotics, Delft University of Technology, the Netherlands. The secondment is part of the European Union-funded project OWHEEL within the framework of the Horizon 2020 Marie Sklodowska-Curie Research and Innovation Staff Exchange Programme.
The OWHEEL project is aimed at investigating various wheel corner concepts with the aim of improving driving comfort, vehicle safety, stability, energy-efficiency and reliability. During this secondment experiments were conducted on the Delft Advanced Vehicle Simulator (DAVSi) with participants. The aim of the tests was to investigate the influence of vibration characteristics, specifically the influence of frequency content, on the applicability of available difference thresholds. This builds on the work that was done during Dr Kat’s secondment to the TU Delft in 2023.
Within the project OWHEEL, difference thresholds can be used to evaluate and compare wheel corner concepts with respect to vibration-induced discomfort. In more general terms, difference thresholds are important to understand the just noticeable difference perceivable by humans and the work done in this secondment aims to provide a better understanding of difference thresholds.
