Dynamic interactions in centrifuge modelling are often induced with external or not controlled sources. This paper presents a method to study Soil-Structure Interaction in centrifuge, with the use of a dynamic actuator developed for centrifuge testing. The dynamic actuator is employed into the model giving the possibility to test the dynamic response of a wind turbine structure, without any additional supporting accessory. The centrifuge soil model was instrumented in order to measure the wave propagation induced by the exited structure. Results regarding the actuator performance and the wave propagation inside the centrifuge model are presented.
