Damping properties of aluminum alloy D16 to reduce the vibration activity of the electromechanical device of an oil and gas station life support system

Relevance. Ventilation and air conditioning systems of oil and gas stations contain electromechanical devices, which operation is accompanied by industrial noise and vibration. This has a negative impact on the wear of the equipment itself and on the health of the operators in the room, as the presence of noise is a harmful production factor. In this regard, reducing the vibration and acoustic activity of electromechanical devices is an urgent scientific and technical task that has attracted the attention of developers for many years. It is known that aluminum, as a structural material, combines high rigidity, strength, and the ability to dissipate energy within its volume, making its application for creating solid-state vibration dampers relevant. This work is devoted to studying the damping properties of aluminum and assessing its potential use as a vibration dampener in damping devices for electromechanical devices in life support systems of oil and gas stations. To achieve this, the authors have carried out the experimental studies of samples made from cast and foamed aluminum alloy D16 using an impact stand. Object. Samples of cast and foamed aluminum alloy D16. Aim. Experimental studies of the damping properties of cast and foamed aluminum alloy D16 to assess the possibility of its use as a damping element in the oscillators of electromechanical devices within the life support systems of oil and gas stations. Methods. Modern approaches to vibration diagnostics, computational mathematics, and measuring instruments. Results. Foamed samples, compared to the cast ones, have greater potential to dissipate the energy of disturbing vibrations from the activity of an electromechanical device and can be used as a damping element.
