摘要：	Brake discs are brake system components that inhibit vehicle motion by converting kinetic energy to thermal energy via friction with brake pads during the process of braking.The vane shapes of a ventilated brake disc play a very important role in dissipating the heat generated by friction.In this study,we applied pillar vanes,rather than the radial straight vanes commonly used,to an internal ventilated structure,and investigated the cooling effects according to the parameterized pillar shapes,the effect on the natural frequency changed by the pillar shape parameters was also considered in order not to occur resonance with other parts of brake system.To optimize the geometry of the pillar vanes at a similar weight with the radial straight vane disc,the Taguchi method was used to determine the rela-tions among the cooling performance,natural frequency and weight according to the various pillar-shape parameters.An experiment based on Taguchi's L-27(310)orthogonal array was carried out using numerical method,and then the three characteristics were simul-taneously analyzed using Grey relational analysis.The optimal parameter values were determined based on the Grey relational grade val-ues,and then a verification simulation was performed to verify the accuracy of the analysis.By the result of the verification,the differ-ences between the prediction and the verification simulation resultswere-1.9%for the disc temperature,1.8%for the 3Z-mode frequen-cy,and 1.8%for the weight of the disc.
