Two simulation analysis case studies for optimization of disc brake assembly level performance and component structural strength using CAE tools were discussed. The first case study discussed was about disc brake assembly level simulation studies to optimize brake pads contact pressures in order to achieve uniform brake friction pad wear during operation, and optimize the guide pin reaction loads. In the second case study, structural optimization of brake torque plate using CAE tools was discussed. The CAE results were validated with the component testing.

This paper presents a methodology for predicting drum brake performance using FEA (finite element analysis) models considering both the mechanical-structural compliance and thermal effects. The methodology for brake torque prediction with FEA models considering the structural flexibility of the brake components alone has been established [1]. The frictional heat generated during braking causes thermoelastic distortion that modifies the contact pressure distribution at the drum-lining interface. In order to capture this thermal effect, a transient thermal analysis is conducted to predict the transient temperature distribution on the brake components. In the thermal analysis, the heat generated at the drum and lining interface is based on the pressure distribution from the compliant mechanical model. Also, the mechanical properties of the brake components as well as the lining friction are dependent on the temperature distribution.
