The aim of this work is to assess the capability of a hydraulic bottle jack to control vibrations. The first stage of the present investigation looked for determining the axial stiffness of the apparatus selected for study, in order to relate its behavior to that of a linear elastic element. To do this, uniaxial compression tests were carried out using a manually controlled servo system. In the second stage, a conceptual application based on the field of mechanical vibrations was considered and solved numerically. The experimental results confirmed the hypothesis of linear behavior and showed that the stiffness coefficient depended on the cylinder height. A numerical modeling was conducted in which the frequencies and the peak displacements of an idealized SDOF system subjected to a random excitation were adjusted based on the experimental stiffness. It was possible to conclude that the equipment analyzed is an effective tool for controlling vibration and reducing displacement when randomly excited and can be calibrated according to the specific conditions of operation. This is an important aspect of safety and functionality for mechanical and structural systems.
