A study of front and back-vented brake disc effecting on braking distance
MetadataShow full item record
Nowadays, the automotive parts industry greatly grows up in Thailand. Brake disc is one of products that play a role in safety area. As a result, the various designs such as front and back-vented brake discs are occurred to improve the performance of usability. Consequently, this study aims to develop the ability of braking dynamometer from 9.7 kg-m.1 kg-m. Moreover, the influence of the front and the back-vented brake disc effecting on braking distance was investigated by single dynamometer referenced JASO C406 for testing condition. Therefore, both of discs were operated under 100, 200 and 300 °C of braking temperature and 2, 4 and 6 MPa of line hydraulic pressure of braking. 2 to 1272 of moment of inertial From experimental works, the test results reflected that the back-vented brake disc created braking distance shorter than front-vented brake disc ostensibly. Besides, there are also diversity of factors as temperature, pressure and initial speed of braking. Especially, the higher temperature caused an increase of deceleration and a decrease of braking distance. Moreover, the higher pressure produced a deduction of braking distance and a rise of deceleration. Finally, the initial speed of braking was directly various the braking distances in same condition.
