Abstract

Reducing squeal from brakes system has become a challenging task for brake engineers. To date, a large number of proposals have been implemented in tackling disk brake squeal but very few solutions have been forwarded in drum brake assembly. This paper attempts to propose a solution to reduce drum brake squeal through structural modifications by using the Finite Element (FE) method. A three-dimensional FE model of an actual drum brake system is developed and validated. First, the baseline FE model is simulated to predict squeal and then several structural modifications are proposed. Finally, dynamic transient analysis is performed for selected modified models in order to confirm predicted results obtained from complex eigenvalue analysis.
