Abstract

Virtual shaker testing is a novel and valuable tool to predict a vibration test response as the coupling effect. This consists of simulating a physical shaker test by modeling the constitutive elements of a vibration test loop. This article presents the implementation and validation of a virtual shaker testing for a high-damped shaker. The shaker is modeled by mechanical lumped elements as a state-space system. In the case of a high damped electrodynamic shaker, the classical experimental modal estimation does not allow a proper identification of the system. This article presents a blocking structure approach as an alternative for shaker parameters determination. The obtained results are implemented in the virtual shaker testing model, simulations are performed and the model is validated by experiments.
