Since tests only provide measurements at sensors, it is interesting to use models to estimate the response at all degree of freedom, correct measurement errors and possibly allow updating of model parameters. The paper gives an integrated perspective on methods developed by the control and structural dynamics communities and in particular methods s...
To analyze brake squeal, measurements are performed to extract Operational Deflection Shapes (ODS) characteristic of the limit cycle. The advantage of this strategy is that the real system behavior is captured, but measurements suffer from a low spatial distribution and hidden surfaces, so that interpretation is sometimes difficult. It is even more...
The need to simulate complex and multi-physics systems is increasingly common in the industry, especially with the advent of mechatronic design. This coupled with economic pressure pushing the industry towards optimizing their products led to a strong increase in simulation time that technological advances can not compensate. An hybrid method analy...
Dynamic computation of braking systems including viscoelastic behaviours. In the context of brake system simulation, the highlight of phenomenon like squeal needs specific methods. We will focus on stability analysis by complex modal analysis. The use of damping system called shims for squeal noise reduction implies that simulations take into accou...
Construction d’un modèle dynamique simplifié constitué de corps rigides et d'un super-élément pour l’optimisation d'un système d'engrenage. Ce travail est basé sur une approche multidisciplinaire qui prend en compte en plus des disciplines classiques pour le dimensionnement des structures mécaniques (statique, dynamique, choix des matériaux..), un...
