Finite Element Analysis on the Influence of the Change of Characteristic Parameters of Brake Pad on Structural Modal
2020
The modal coupling of disc brake disc and brake pad is one of the main causes of brake noise, so the structural modal of the disc and brake pad is very important for the research of brake noise. In this paper, finite element theory is used to analyze the influence of the characteristic parameters of the brake pad on the structural modal. We use modal analysis to calculate the modal frequency and modal shape of the brake pad that has the different thickness, the depth and width of the groove, and the chamfer. According to the simulation results, the thickness of the brake pad, thegroove depth of the brake pad, the groove depth of the brake pad and the size of the brake pad chamfer all have influence on the modal characteristics of the brake pad structure, especially, the thickness of the brake pad has the greatest influence.Therefore, changing the thickness of the brake pad and the depth of the brake pad groove can be a potential way to reduce the brake noise of disc brakes.
