차량용 브레이크 디스크와 패드의 온도 해석 = Analysis of Temperature Distribution of the Automotive Brake System

다국어 초록 (Multilingual Abstract)

It is crucial for the safety of the passengers to design the brakes of the vehicle appropriately. One must accurately estimate the temperature increase of the brake during the braking operation and provide sufficient cooling or heat loss to maintain the stress below the allowable limit of the braking system.
In this study three models were used to obtain the temperature distribution during the braking process of an actual part was investigated and compared. A two-dimensional axi-symmetric model was sufficient for obtaining the temperature distribution; however, it was found to be unsatisfactory for analyzing the stresses. In the case of the tree-dimensional portion of the model the temperature distribution turned out to be similar to the actual temperature measurement. However, under repeated braking conditions the maximum equivalent stress turned out to be greater that the yield stress; thus, the current design requires research.
