Brake squeal is an instability issue with many parameters. This study attempts to assess the effect of thermal load on brake squeal behavior through finite element computation. The research can be divided into two parts.The first step is to analyze the thermal conditions of a brake assembly based on ANSYS Fluent. Modeling of transient temperature and thermal-structural analysis are then used in coupled thermal-mechanical analysis using complex eigenvalue methods in ANSYS Mechanical to determine the deformation and the stress established in both the disk and the pad. Thus, the influence of thermal load may be observed when using finite element methods for prediction of brake squeal propensity.A detailed finite element model of a commercial brake disc was developed and verified by experimental modal analysis and structure free-free modal analysis. This analysis includes prediction of disc thermal deformation and a complex eigenvalue analysis to evaluate its effect on squeal propensity.The finite element model should be parameterized in order to investigate the effect of variability. The process includes geometry simplifications to reduce calculation time, allowing for more configurations to be computed. Several parametric studies were conducted to assess the effects of the friction coefficient, of the rotating direction and velocity, Young’s modulus, etc.
