In the present study, an investigation of disc brake squeal is done by performing complex eigenvalue analysis using finite
element software ABAQUS /standard. A positive real part of a complex eigenvalue is being seen as an indication of instability.
Though the FE simulations can provide guidance, it will rather be trial-and-error approach to arrive at an optimal configuration and
also one may need to run many number of computationally intensive analyses to formulate the ‘input-out’ relationships for
possible prediction. Hence, in the present investigation, a novel approach is proposed by integrating the complex eigenvalue FE
analyses with structured DOE. The proposed approach is aimed towards prediction of optimal pad design through the various
factors of the brake pad geometrical construction.
