Parametric model order reduction for efficient frequency response evaluation

Autor: Cool, Vanessa, Naets, Frank, Rottiers, Ward, Desmet, Wim

In many mechanical applications, a design optimization is performed on the frequency response functions of the mechanical system. In this work, a novel model reduction technique is explored for the parametric analysis of the frequency response functi

Fatigue damage precursors identification and control procedure is developed for nonlinear aero-structures and dynamic systems exposed to realistic vibratory conditions. The identification is achieved by connecting nonlinearities between macro-and mic

Noise, ill-conditioning and sensor placement analysis for force estimation through virtual sensing

Autor: Tamarozzi, Tommaso, Risaliti, Enrico, Rottiers, Ward, janssens, Karl, Desmet, Wim

The knowledge of loads acting on machines and components is crucial in many application fields. Input estimation though is a very challenging inverse problem with which researchers have struggled over the last decades. Several issues related to ill-c

An accurate stress or strain history at fatigue critical locations is often needed for a fatigue assessment. Unfortunately it is not feasible to install strain gauges as these fatigue hotspots. This contribution compares two techniques to obtain a re
