In the frequency domain, the multi harmonic balance method is used to study the dynamic behavior of bladed assemblies with nonlinearities caused by dry friction dampers. Associated to a Macroslip contact model, this method is generalized to be adapted to a multi degrees of freedom mass-spring system characterized by the cyclic symmetrical property. The influence of contact parameters is investigated and their capacities in minimizing the magnitude of nonlinear responses of the system are studied. The effects of mistuning caused by contact parameters are discussed and its influence on the dynamic behavior of the structure is emphasized.
