  abstract = {For many technical applications it is necessary to avoid or to reduce
	vibrations. Factors benefiting from vibration reduction are for example
	the durability of the application, which is increased, as well as
	cost expenses and the level of noise, which are both decreased. Rough,
	bolted interfaces are common in most machines and can be used as
	damping devices with some effort. Perhaps in future such contact
	surfaces could be used as damping devices at the interfaces of an
	automotive engine or exhaust system. Nevertheless it is difficult
	to predict the effect of a change in contact interface parameters
	on the dynamic behavior of the entire mechanical system. Therefore
	a method for calculating the steady state behavior of elastic multi-body
	systems was developed. The basis of this method is a finite element
	model of each contacting unit. On each model a modal reduction is
	applied in order to reduce the degrees of freedom. The method of
	Ritz and Galerkin is used to calculate the frequency response functions
	of the reduced system including contact. This method allows the calculation
	of the steady-state behavior of elastic multi-body systems with rough,
	bolted contact interfaces, by taking the pre-stress of the bolts,
	the roughness and the friction coefficient of the contacting surfaces
	as parameters. In order to verify calculated results, a test stand
	was built. The comparison of calculated and experimental results
	showed a satisfying correlation.},
