Abstract
Mechanical structures are commonly jointed using fasteners such as rivets or bolts arranged in various configurations depending on the required performance. They are an important part of the system and can influence its dynamic response. In this paper, two beams are connected in a single row rivet lap joint and modelled using the spectral element method (SEM). The equivalent spectral model represents the rivet joint and the beams. The identification of dynamic characteristics of the system is validated by comparing the results to the commercial finite element- ANSYS. It is found that the vibration responses obtained with SEM are in good agreement with the dynamic responses estimated via FEM. The advantage of using SEM are the reduced number of elements in the mesh and high accuracy in the vibration response prediction.
