Abstract: Foam-filled fluid (FFFluid) is an innovative material technology that can be used to design anti-vibration devices. This material technology is able to dissipate energy via a number of mechanisms due to the combination of elastic and buckling properties of foams, viscosity properties of fluids and the method of packing the material. The relationship between the energy isolation mechanisms can be altered by modifying the properties of the constituent components which provides significant opportunity for tailoring the response of the isolator to meet the different demands placed upon it. While previous studies have characterized the FFFluid shock absorbers, this paper covers the characterization of the mechanical properties of FFFluid vibration isolators. The work presented here starts by studying the parameters that have an effect on the performance of an FFFluid isolator theoretically. Then, the influence of a selected number of factors on the transmissibility of an FFFluid isolator is

Abstract: Single and multi-axis shaking tables are an efficient way for the testing of a large number of systems. Among the possible fields of application, the civil engineering field stands out for the testing of structures, or part of them, both on a reduced and on a full scale. This work belongs to this field and concerns the design of a small size (1200 mm x 2000 mm) hydraulicactuated single-axis shaking table, for the simulation of seismic loads on civil structural elements that weight less than 1200 kg. According to a typical mechatronic approach, the choice of the hydraulic components, the design of the mechanical system and the design of the control system were synergically carried out. Eventually, the system was built and preliminary experimental tests were performed for the evaluation of its functionality.
