Abstract: Using computer aided engineering (CAE) simulation methods and experimental testing methods, CAE strength analysis, temperature field analysis, and noise testing analysis of a light truck disc brake system are carried out. The results show that under the braking condition of an initial speed of 80 km/h, the yield strength, thermal stress, and temperature rise curve of the key components of the disc brake system met the design objective requirements. At the same time, on-site testing shows that there are no reliability issues related to the strength and thermal stress of the disc brake system. The development process combining simulation analysis and actual vehicle testing has improved the reliability of the disc brake system, shortened the component development cycle, reduced costs and increased efficiency, and effectively enhanced the product competitiveness of this light truck model.
