Abstract

In the previous paper [1], the formula of the contact pressure distribution in the steady wear state for drum brake system was derived. The contact pressure distributions on the leading and trailing shoes were found to be different and larger on the leading shoe. Using these contact pressure distributions, it is easy way to calculate the braking torque. Assuming the varying position of the shoe pin, the optimization problem can be formulated by requiring the optimal pin position corresponding to maximal braking torque. The steady wear states and optimal designs were specified for both shoes. The elastic displacement field of the drum brake at the optimal contact pressure distribution is calculated by the finite element system ABAQUS. At given rigid body rotation of the shoe, the wear in the leading and trailing shoes in the steady wear state can be easily found.
