Abstract: In this paper, the fracture failure of the air horn bracket is studied based on a vehicle model market. In view of the rupture problem of the horn bracket, this paper makes a deep analysis from the factors of the rupture of the sheet metal bracket. By using computer aided engineering (CAE) for strength analysis, modal analysis and bench test, the root cause of the problem is determined and optimized, and the improved structure is verified by bench vibration test, and finally the use requirements are met and the risk of fracture is completely eliminated. In this paper, the fracture factors and verification methods are summarized to accumulate experience for optimization and verification of similar problems.

Key words: Air horn bracket fracture; Bench test; Structural optimization
