Combining a Nonlinear Static Analysis and Complex Eigenvalue Extraction in Brake Squeal Simulation

This paper presents a new functionality of ABAQUS/Standard, which allows for a nonlinear analysis prior to a complex eigenvalue extraction in order to study the stability of brake systems. Friction-induced dynamic instabilities are caused mainly by two phenomena: coupling of two neighboring modes and negative friction-velocity gradient. Both of these phenomena can be modeled with ABAQUS. A simplified brake model, consisting of only a rotor and pads, is used to illustrate this new capability.
