- Analytical methods have been developed to determine equivalent material properties of brake dampers for their inclusion in a system model. A multi-layered model of a damper is reduced to a single layer model. The material properties for this single layer model are determined from a simulation of a bench-top, damper/shoe/lining impact modal test. Two different dampers are considered. The damper's response is confirmed by experimental results. A complex-eigenvalue analysis is then presented to show the effect the two brake dampers have on the braking system. Conditions of the eigenvalue analysis were set to match noise events in a squeal rig test. The eigenvalue analysis shows a stabilization of the braking system with the equivalent damper models. The results are confirmed with dynamometer testing.
