  abstract = {In forced systems with cyclic symmetry localization can occur due
	toparameter uncertainties. Often, Monte-Carlo simulations are used
	to findregions, where the system response is sensitive to parameteruncertainties.
	These simulations require a large computation time.Therefore, an
	approximate method to calculate the envelopes of thefrequency response
	functions is developed in this paper. An example of anonlinear system
	with cyclic symmetry is a bladed disk assembly withfriction dampers.
	Friction dampers can be installed underneath the bladeplatforms of
	turbine blades. Due to dry friction and the relative motionbetween
	blades and dampers, energy is dissipated, which results in areduction
	of blade vibration amplitudes. By optimizing the mass of thefriction
	dampers, the best damping effects are obtained, which lead toan increase
	in the reliability of the turbine. In this paper, thecalculated response
	of a mistuned bladed disk assembly with frictiondampers is discussed.
	An approximate method is developed to calculatethe envelopes of the
	corresponding frequency response function forstatistically varying
	eigenfrequencies of the blades. Regions wherelocalization can occur
	with a high probability, are calculated by thismethod.},
