Abstract:

In this seminar, we will discuss the concept of coupling and decoupling of substructures, discuss what problems occur when applying substructuring with measured components and what tricks can help getting good results from such Frequency-Based Substructuring approaches. We will then discuss how substructuring can be used to find the dynamic properties of linear interfaces and show results on a simple example.

Biography:

Francesco Trainotti is an engineer and PhD student at the Chair of Applied Mechanics at the Technical University of Munich, where he has been working since 2019. He conducts academic and industrial research in the areas of experimental and numerical structural dynamics, vibration analysis, and systems identification. He received his Bachelor's Degree in Industrial Engineering from the University of Trento (IT) in 2015, followed by a double Master's Degree in Mechatronics from the University of Trento (IT) and in Mechanical Engineering from the Technical University of Munich (DE) in 2018.

Daniel Rixen, (b. 1967) received his engineering degree (electro-mechanics) from the University of Liège (ULg, Belgium) and an MSc degree in Aerospace Vehicle Design from the College of Aeronautics in Cranfield (UK). He obtained his doctorate degree from ULg in 1997, supervised by Professor Géradin. After a research assistantship at the Center for Aerospace of the University of Colorado (USA), he became in 2000 a full professor at Delft University of Technology (The Netherlands) where he held the Chair of Engineering Dynamics. Since 2012 he is heading the Department of Applied Mechanics at TUM. Daniel has worked for more than twenty five years on theoretical, numerical and experimental aspects of the dynamics of structures and systems. His activities encompass simulations and measurements of vibrations as well as domain decomposition for parallel computing, modelling of multiphysical systems, model reduction techniques and robotics.
