  • Studies on brake system recently are focused on braking performance, especially the consideration on safety of braking system in an extreme situation and reduction of vibration and noise during braking operation. The thermal crack and Judder from the friction between brake disc and pad can bring the threaten of passengers' safety in the end. Braking force comes from the change of kinetic energy to friction energy. Since heat energy is developed from here, the analysis on thermal stress and thermal strain can be the good data when selecting the material of brake pad and designing heat radiation holes on the disc and it will also be the data when designing the thickness of the disc. This paper is intended to show a creative design method by suggesting the thermal analysis data through FEM study and using shape design parameters.

  • This study aims to improve the heat performance of motor cycle disk due to the number of holes by analyzing 6 kinds of disk models. This disk performance depends on the efficiency at emitting the heat. To raise the efficiency of heat emission, holes with circle or another configuration are made on disks to emit heat fast. The distribution of temperature, heat flux, deformation and stress are analyzed. As the number of holes on disk increases, the performance of heat emission is improved. Equivalent stress is decreased and durability is improved as the number of holes on disk increases. Though the number of holes on disk is increased, the performances of heat emission and durability do not become better. The optimal model can be found by comparing models each other through this analysis result. Through this study result, the configuration of motor cycle disk is designed with optimal heat emission and durability by comparing models.
