Abstract

In this paper, by the use of elastic multibody dynamics and a master–slave contact approach with penalty formulation, computationally efficient time integrations of a brake system are performed for constant and time-dependent input parameters. As a result, the amplitudes of the friction-induced vibrations and the contact forces at the disc–pad interfaces are predicted. Besides, system outputs are viewed in phase diagrams, and the creation of a stable limit cycle for a low friction coefficient is identified. In this way, conclusions on the stability of the system are drawn, and statements based on frequency-domain analyses are complemented. Finally, a distinct need for a new criterion that quantifies the squeal propensity of such systems in the time domain is identified.
