Multibody Systems

The focus group “Multibody Systems” consists of Hans Fischer Senior Fellow Prof. Michel Géradin (Emeritus Professor, University of Liège, Belgium), Hans Fischer Fellow Dr. Karin Nachbagauer (University of Applied Sciences Upper Austria),  their host Prof. Daniel Rixen (TUM Department of Mechanical Engineering) and Dr. techn. Andreas Zwölfer (TUM Department of Mechanical Engineering). The activities of this focus group are primarily centered around the interplay between modeling, simulation and optimization of nonlinear dynamic systems, with special focus on flexible multibody systems. On the one hand, new formulations considering floating frame of reference formulations for the modeling of rigid and flexible multibody systems have been presented and will be further developed. On the other hand, new approaches for the intelligent optimal control of multibody systems for future digital twin technologies are investigated within the focus group. Efficient numerical methods for design and simulation of multibody systems as e.g. robots, represent an important challenge in the engineering dynamics community and are at the center of our scientific collaboration in the focus group.
