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 centered on the interplay between modeling, simulation, and optimization of nonlinear dynamic systems, with special focus on flexible multibody systems. On the one hand, we will develop new formulations for the modeling of rigid and flexible multibody systems that take floating frames of reference into account. On the other hand, new approaches for the intelligent optimal control of multibody systems for future digital twin technologies will be investigated. Such efficient numerical methods for design and simulation of multibody systems such as robots, for example, represent an important challenge in the engineering dynamics community and are at the center of our scientific collaboration.

Prof. Géradin holds a TUM-IAS Hans Fischer Senior Fellowship awarded by Siemens AG.
Prof. Nachbagauer holds a TUM-IAS Hans Fischer Fellowship awarded by Siemens AG.
