Squeal noise is an on-going problem of the automotive industry and it has been researched via various methods. The approach of squeal noise through CAE-based Complex Eigenvalue Analysis (CEA) is commonly used in the current industry and is being utilized to derive prompt counter-measures. However, the results of a one-shot analysis based on a deterministic model have limitations that only show an average representation of various uncertainties. These restrictions can lead to distrust of CEA results such as deriving the counter-measure study.
