Vibration properties of many assembled mechanical systems depend on frictional damping in bolted joints. The nonlinear transfer behaviour of the frictional interfaces often provides the dominant damping source in built-up structures and plays an important role in the vibration response of structures. At the University of Stuttgart, three different approaches were compared for modelling damping, based on a truss structure, a motor vehicle control unit and a car engine.

1 INTRODUCTION

The dynamic properties of most assembled mechanical systems depend on the frictional damping in joints. The non-linear transfer behaviour of the frictional interfaces often provides the dominant damping mechanism in assembled structure and plays an important role in the vibratory response of the structure. This article gives a short overview of three different approaches to damping modelling based on the contact distribution in joints. It discusses the modelling by local joints, by thin layer and zero...
