dr.ir. R.G.K.M. Aarts (Ronald)

Ronald Aarts is Associate Professor in the group Structural Dynamics, Acoustics and Control (SDAC) of the faculty Engineering Technology (ET). He has a background in Applied Physics and obtained his MSc and PhD both at the Eindhoven University of Technology. In 1994 he joined the University of Twente initially working on the fluid induced forces in centrifugal pumps. From 1997 onwards he supervised several projects related to robotised laser welding.

His current research is in the area of (flexible) multibody system dynamics with a focus on (numerical efficient) modelling, system identification, parameter estimation and links to control and design challenges. He coordinates the in-house development of the software package SPACAR in which a non-linear finite element formulation is implemented that offers unique benefits for the analysis and simulation of e.g. manipulators with interconnected rigid and flexible parts. He researches the development of low order and reduced order models that are well-suited for design optimisation. Fully non-linear or linearised models are integrated with control systems to capture the dominant behaviour of mechatronic systems.

He teaches in second and third years’ Bachelor modules. The above mentioned research topics are addressed in more specialised Master and post-Master courses that can be tailored to a specific (e.g. industrial) audience.
