Modal analyses of an S-cam drum brake assembly, using finite element analysis, are presented. A friction interface contact pressure-dependent model for the coupling between the lined brake shoe assembly and the brake drum is described. Using this model, natural modes and frequencies are predicted which compare well with measured data for the brake assembly. A parametric study of brake design and performance variables is presented which predicts the noise propensity of the brake design based on the binary flutter model. Good agreement with the measured brake noise and trends, experience and other published work on S-cam brake noise is shown.
