Complex Eigenvalue Analysis (CEA) is a commonly used method for predicting brake noise occurrence. However, it tends to yield overestimated results due to the inheritance property of the CEA method.
Efforts are being made to improve the accuracy of brake noise predictions by developing new processes that go beyond the traditional CEA methodology. Researchers are investigating whether modifications to the mathematical formulation of CEA could be implemented to minimize the tendency for overprediction.
What are alternative processes / potential modifications to the mathematical framework (CEA) to achieve more accurate and reliable predictions in the field of brake noise analysis?
