Simulations of Structurally Closed-Loop Coupling and Experimental Study on Drum Brake Squeal of Commercial Vehicles
Published October 17, 1994 by Society of Automotive Engineers of China in China
In this paper, the structurally closed loop coupling model of drum brake squeal is established on the basis of experimental study which consists of three stages. 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.
