In this paper, the structurally closed loop coupling model of drum brake squeal is established on the basis of experimental study. The relevant equations of structural dynamics have been derived by applying Hamilton Principle, moreover; the model for numerical computation is formed. And the influence of structural parameters, especially that of structure of brake backplate, upon the drum brake squeal is studied in detail through computational analysis. The results of the theoretical study is consistent with that of experimental study quite well. Both the experimental study and theoretical study have proved that the brake squeal of the drum brake system studied in this paper can be suppressed through stiffening the brake backplate. It is pointed out that the structural parameter matching between brake drum substructure and the brake backplate, brake shoe, brake operation system and brake pump substructure is very important to drum brake squeal.
