The Experimental Dynamics Laboratory of the LEDA Research Centre (Laboratory of Earthquake engineering and Dynamic Analysis) is equipped with a series of important scientific equipment that allows to perform dynamic tests in a wide range of frequencies and payloads, fully involving the civil, mechanical and aeronautical engineering sectors, the transport industry and the energy and defence sectors.
The main research infrastructure of the Experimental Dynamics Laboratory is the system of two six-degree-of-freedom vibration tables measuring 4 m by 4 m (Figure 5) built by Bosch-Rexroth specifically for LEDA.
The activities of the Experimental Dynamics Laboratory are aimed at developing research and teaching activities and third-party consultancy services in the fields of Building Science, Structural Engineering, Structural Dynamics and Seismic Engineering.
The topics of interest include the definition of the dynamic behavior of traditional and innovative materials and of full-scale and scale structural models, the development of techniques for the mitigation of seismic risk and for the control of vibrations, the calibration of finite element models of complex structures, the study of methods for structural monitoring and for the identification of incipient damage and the study of intelligent structural systems.
The topics covered are transversal to all degree courses included in the educational offer of the Faculty of Engineering and Architecture of the University of Enna “Kore” and the laboratory facilities are available to students for internships, degree theses and research doctorates.
The Experimental Dynamics Laboratory is also active in the provision of testing services and technical-scientific consultancy in the field of Structural Engineering and in the sectors of Electrical Engineering, Energy, Defence and in support of companies and industries in the Civil Engineering sector.
The Experimental Dynamics Laboratory is engaged in various theoretical, numerical and experimental research activities briefly described below. On these topics, training courses, degree theses or research projects can be activated on active PhD courses:
The experimental activities of scientific research, teaching support and third-party consultancy of the Experimental Dynamics Laboratory are carried out within different environments in which the scientific equipment described below is present:
