Abstract

In modem vehicle,braking system is one of the most important systems in order to prevent accidents.Braking system is used to slow or stop the vehicle.When braking, the friction between pads and disc rotor will generate heat and will result on temperature rise.The rise in temperature usually will contribute to disc brake problem such as thermal crack and brake fade.Therefore, controlling the thermal stress of disc brake is a must in order to prevent these problems.This research will focused on thermal stress analysis on gray cast iron disc brake rotor for NGV vehicle for steady state and transient condition.The gray cast iron disc brake for NGV vehicle is designed and modeled by using SolidWorks.Heat flux and convectional heat transfer coefficient was calculated to determine the temperature distribution of disc brake.Thermal stress of disc brake was predicted by using finite element analysis technique in ANSYS and the effect of NOV to thermal stress distribution of disc brake rotor was analyzed to determine whether the disc brake is safe to use.As a result,the highest temperature distribution recorded for NGV vehicle gray cast iron disc brake is still below the maximum service temperature of gray cast iron disc brake and the value of equivalent (vonMises) stress also below maximum tensile strength.
