Abstract: Brake Rattle noise is one of the noise, vibration, harshness (NVH) problems that has long plagued automobile manufacturers and brake suppliers. In order to solve this problem, based on the brake development project, this paper establishes the single degree of freedom model and mechanical analysis model, and determines the main factors that affect the brake Rattle noise. At the same time, by the vehicle test verification and analysis, the role played by the main factors of the brake system in the process of the brake noise generation is described. The analysis results show that the gap control of the noise generation position is the key internal factor affecting the noise. In the process of research and analysis, various factors and methods to solve the noise problem are also sorted out, which could provide the reference for Automobile enterprises and brake suppliers to solve similar noise problems.
