Abstract
Minimizing brake squeal is a quite important issues in the development of high performance baking systems. This paper proposes a design optimization method for disc brake systems to reduce brake squeal considering robustness against changes on contact surface pressure distribution between the brake disc and pad, which can be used at the conceptual design stage. In this method, a simplified analysis model is developed considering surface pressure distribution and a design criterion to evaluate brake squeal performance is proposed, then, an optimization problem is formulated with maximization of the brake-pad contact area as the objective function, and the optimization problemis solved using a genetic algorithm. The proposed method is then applied to design problems to illustrate the effectiveness of the proposed design method.
