Abstract

During the braking process, frictional heat generation between brake strip and brake block can lead to high temperatures, significantly affecting the braking performance. This paper proposes a novel knee impact test method and innovatively investigates the effect of brake friction surface texture shape on braking performance. A comparative evaluation of the braking performance of different surface textures is conducted using the new knee impact test, with a focus on studying the temperature rise during braking to optimize the brake system. Research findings indicate that the best braking performance was achieved when friction surface texture of the brake block was rhombus-shaped with a diagonal ratio of 5:5. By implementing this improved brake design, the maximum temperature during braking was reduced from 184.44∘C to 75.963∘C, resulting in a significant reduction in thermal stress from 155.22 MPa to 64.40 MPa. Moreover, the acceleration and brake distance are extracted and compared with the target values of Euro NCAP. The improved brake acceleration exhibits stability and a deviation from target value within 10%. Additionally, the deviation between our brake distance and target distance is −3.63%. These results provide a valuable reference for improving the braking performance of braking systems in the new knee impact test.
