Finite Element Analysis on the Brake Shimmy of Drum Brake

Abstract:

This paper adopts finite-element method to analyze and test the factors which influence the brake shimmy. Based on the prototype of a particular heavy truck, finite element model of the brake shimmy about drum brake is developed upon the mechanism analysis of drum brake. The reasons that drum brake has oscillation phenomenon during braking process is analyzed by simulation and calculation the transient response in this process. Tests indicate that results of finite element analysis are consistent with the conclusion of real vehicle road test.
