About Me

Ronald Aarts is an Associate Professor in the Applied Mechanics and Data Analysis (AMDA) research group, which is part of the Faculty of Engineering Technology (ET). He is trained in Applied Physics, obtaining both an MSc and a PhD from the Eindhoven University of Technology. He joined the University of Twente in 1994, and initially worked on fluid-induced forces in centrifugal pumps. From 1997 onwards, he supervised various projects in the area of robotic laser welding.

Dr Aarts’ current research is in the area of flexible multibody dynamics, with a focus on numerically efficient modelling, system identification, parameter estimation and links to control and design challenges. He also coordinates the in-house development of the SPACAR software package. This implements a non-linear finite element formulation that offers unique benefits in terms of the analysis and simulation of devices in which rigid and flexible parts are interconnected, such as manipulators. He is also developing low-order and reduced-order models for use in design optimization. Fully non-linear models or linearized models are integrated with control systems to capture the dominant behaviour of mechatronic systems.

Ronald Aarts teaches elements of second-year and third-year Bachelor’s modules. The above-mentioned research topics feature in more specialized Master’s and post-Master’s courses, which can be tailored to specific audiences (e.g. from the industrial sector).
