Joints play an important role in most mechanical applications and the prediction of the dynamical behavior of jointed structures is a challenging task in structural dynamics. Their inclusion leads to, for example, shifts of the resonance frequencies or of the maximal response amplitude within a resonance due to damping effects. In this paper, the focus is on investigating the behavior of a jointed structure over a broad range of excitation frequencies within the frequency domain corresponding to the stationary behavior in the time domain. Due to the nonlinear forces, it is not possible to directly perform an analytical transformation of the system equations into the frequency domain, so the Harmonic Balance Method (HBM) is applied here. In the framework of the HBM it is assumed that a harmonic excitation of the system leads to a harmonic response. The calculation procedure is applied to a friction oscillator containing a bolted lap joint, which is modeled via different Finite Element models with a corresponding three dimensional contact law. The calculation results are compared to each other.
