Experiments and simulations of the structure Harmony-Gamma subjected to broadband random vibrations

The structure Harmony-Gamma is a metallic assembly representative of an industrial for which the vibratory response influenced by apparition nonlinear phenomena within two specific types joints, first corresponding to friction joints and second elastomer joints. present study extends previous work based on experiments numerical simulations subjected harmonic vibrations [1]. More specifically, vibrational behaviour random broadband excitations studied. Broadband are performed experimentally, in order provide understanding effect both Additionally, global methodology finite-element modelling use Harmonic Balance Method prediction stochastic excitation proposed. It demonstrated that model has been validated against experimental tests can furthermore be used achieve refined their origin.
