- This project outlines the effect of changing Young’s modulus, Poisson’s ratio, and shear modulus on the natural frequencies of brake pads. It aims to improve the understanding of the influence of friction material properties on the natural frequencies and observe how the natural frequency changes with the changes in the properties of the composite brake pad friction material. In addition, two different brake pad models (Pad-A and Pad-B) were designed using CATIA V5 software to study whether different pad aspect ratios can affect the influence of friction material properties on the natural frequencies. The finite element analysis (FEA) was utilized to derive the natural frequencies and mode shapes using ABAQUS software. In addition, an experimental modal analysis (EMA) was performed on Pad-A to evaluate the accuracy of the FEA. Furthermore, the factorial analysis was applied on the obtained natural frequencies for each pad to find out the material properties that have the main effect on the natural frequency and the relationship between each property and the natural frequency using MINITAB software. The results indicated that increasing transverse Young’s modulus can increase the values of natural frequencies. On the other hand, reducing longitudinal Young’s modulus, Poisson’s ratio, and shear modulus in all directions can increase the values of natural frequencies. Therefore, the study deduced that transverse Young’s modulus and Poisson’s ratio must be taken into account when choosing a suitable friction material for brake pads.
