Abstract
This paper proposes a design method for disc brake systems that aims to reduce brake squeal and improve cooling performance. The minimization of brake squeal, one of the most important issues that must be addressed when developing high-performance braking systems, can be achieved by maximizing the natural frequencies of the brake system structure. Maximizing the cooling performance of the brake system is an equally important design issue that affects braking forces and the performance of the braking system. In this paper, a topology optimization method is employed to maximize not only the natural frequencies but also the cooling performance in a simplified model of a brake disc. The optimization problem is formulated as a multi-objective problem, using a level set method in order to achieve clear structural boundaries in the obtained optimal configurations. Several numerical examples are provided to confirm the validity and utility of the presented design method.
