TEMPERATURE AND CONING ANALYSIS OF A VENTILATED DISC BRAKE USING AXISYMMETRIC MODEL

摘要

The disc brake used in the automobile is divided into two parts: a rotating axisymmetrical disc, and the stationary pads. The frictional heat, which is generated on the interface of the disc and pads, can cause high temperature during the braking process. The object of present work is determination of temperature distribution and comparison of simulation results and experimental results in the disc by 2D thermal analysis using axisymmetric model. The influence of initial velocity and deceleration on coning of the brake disc was also investigated. The transient thermal simulation is used to characterize the temperature field of the disc with appropriate boundary conditions.
