摘要

The main objective of the present study is to introduce the optimal brake pad design in order to reduce squeal noise through the various design factors using statistical technique. A new approach is considered by integrating a commercial finite element software package (ABAQUS) with response surface methodology using software package (MINITAB). The finite element model of brake assembly is developed and correlated with hammering test of each brake component and brake assembly. The complex eigenvalue analysis is performed to assess the brake stability. Finally, response surface methodology is combined with complex eigenvalue analysis to identify the most design factors that significantly influence reduction of squeal noise. It is observed that increasing Young's modulus of brake pad in combination with increasing chamfer and reducing the distance between two slots reduces the squeal noise.
