On the improvement of NVH simulations using uncertain FE brake models

Abstract : Numerical simulation of mechanical phenomena is under constant development due to the exponential growth of computer power. This facilitates the fast implementation of more and more fine and complex numerical studies performed at different scales. At the preliminary design stage, optimization strategies and non-deterministic methodologies are also increasingly common. This paper presents results from both experimental and numerical designs of experiments (DOE) for the study of the influence of the variability linked to the disk brake squeal. The objective is to assess the extent to which more representative information can allow the designer to evaluate solutions towards the squealing phenomenon. A key point is to define a strategy for the management of the large amount of solutions both for the complex frequency analysis and the transient analysis. Another key point is whether the criteria used for deterministic studies, will be able to aggregate all the behaviours of a family of braking systems. Methodologies are proposed to answer these questions and numerical results show the benefits of enrichment of numerical simulations for squealing phenomena detection.
