Abstract

The purpose of this study was to investigate the vibration characteristics caused by front and back vented brake disc which were physical shape difference. According to theory of heat transfer, the heat transfer rates of two types of brake disc were different and play a role in the deformation during usage. The single dynamometer was conducted to the experimental work as an engineering tool with boundary condition of JASO C406 standard. The measured one degree of freedom (DOF) acceleration signals on the brake caliper were analyzed. The results obviously discovered that the back vented brake disc was able to reduce vibration maximum to 43.5% comparing to the front vented brake disc in case of the braking temperature 200°C with initial breaking speed 50 km/h and the hydraulic pressure of 4 MPa. Besides, the hydraulic pressure at 4 MPa played a maximum role in the vibration. Furthermore, the initial braking speed and the braking temperature were also the important factors.
