Modeling the Cooling Characteristics of a Disk Brake on an Inertia Dynamometer, Using Combined Fluid Flow and Thermal Simulation

Braking System Modeling and Brake Temperature Response to Repeated Cycle

“…Empirical brake model is preferred since non linearity due to vacuum booster operation is taken into account. The pedal force/travel characteristic curve has three distinct regions [6]. First, the pedal moves under constant applied force from the origin to a point called "Jump-in".…”

“…One way to improve brake performance is maximizing convective cooling from the rotor to surrounding airflow. Nutwell and Ramsay [6] developed CFD (Computational Fluid Dynamics) model of disc brake assembly installed on an inertia brake dynamometer. Combined with physical test, the effects of cooling air flow, braking energy input rate, and rotational speed on brake operating temperatures can be evaluated with the proposing CFD model [6].…”

However, the thermal load was given, not derived from real braking condition obtained from simulation or experiment.…”
