Abstract

This paper deals with the investigation of a jointed structure in the frequency domain. Because of the nonlinearity of most jointed systems the steady state response shall be calculated utilizing the Multiharmonic Balance Method (MHBM). In the framework of this method the response displacements of the system are assumed to be periodic and are approximated by a Fourier-type series expansion considering a limited number of harmonic parts. The MHBM is presented for a system containing a bolted lap joint. For the contacting bodies small deformations and linear elastic material behavior are assumed. The system will be modeled with the Finite Element Method (FEM) using so called Zero Thickness (ZT) elements for discretizing the contact plane. Since this contact area is known and only small relative displacements occur, the suggested contact element is well suited for the present problem. The ZT elements contain a three-dimensional nonlinear contact law considering dry friction effects. A model updating process is used to fit the calculation results with respect to the measured data of a real system. © The Society for Experimental Mechanics, Inc. 2013.
