Tavola vibrante triassiale: validazione di procedure per test dinamici accelerati con vibrazioni random gaussiane

The aim of the thesis is to verify the existing relation for the prediction of test length during dynamic accelerated tests by means of random gaussian excitation given byan electrodynamic tri-axial shaker. After the validation of the relation for 1-D excitation the experimental campaign aims to extend this relation for multi-axial excitation in order to reproduce the real operating conditions of a mechanical system.
