To accelerate the development of non‐linear, friction‐excited systems, i.e. automotive friction brakes, novel test procedures are being developed. These include the study of the system's forced vibrations. However, there is a lack of knowledge concerning feasible test procedures, the assessment of the gathered data, and the possible vibration phenomena. In this context, the contribution at hand discusses vibrations in non‐linear, forced, friction‐excited systems. In the pre‐flutter regime proposed criteria for identification of parameter regions in which limit cycle oscillations can occur are challenged. In the post‐flutter regime frequency spectra for different excitation conditions are studied. (© 2015 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
