Optimization of the brake parameter for a disc brake system to improve the heat dissipation using taguchi method

Disc brake rotor was proved to have better heat dissipation performance than drum brake as more exposed surfaces had provided to improve the heat transfer. However, overheated surfaces that caused brake fade was still a possibility. In this research, three ventilation parameters of disc brake rotor (number of rotor holes, number of slots and diameter of rotor holes,) associated with three factor values levels ranging from minimum, average and maximum were studied experimentally by utilising of Taguchi method. The result obtained from the experiment has pointed that disc brake rotor design with twenty-four 4mm diameter holes and six slots was the optimum design while number of ventilation slots was the most significant parameter that contributed at a rate of 45.25% in heat dissipation performance.
