ELESA anti-vibration mounts

Vibration damping according to ELESA Vibrations are often an undesirable phenomenon that is harmful to the machines that generate them, to working conditions and to people's health. The world of mechanics already has effective solutions to prevent the excess vibrations produced by machines with moving parts, such as motors, pumps or air treatment systems, from interfering negatively with their proper functioning. or their activity. However, given the magnitude of the undesirable effects attributable to vibrations and the repercussions in terms of loss of system efficiency, the scientific world continues to explore and develop new solutions and new "metamaterials" to stop or reduce the spread vibrations in the air or in solid bodies. A group of researchers from the University "Politecnico di Torino", in collaboration with researchers from other European universities, in a study recently published in the scientific journal "Matter" (Optimized structures for vibration attenuation and sound control in nature: A review) observed the phenomenon in nature, focusing on the solutions adopted by animals such as woodpeckers, which pierce the trunks, or certain moths, whose wings are structured in such a way as not to be heard by bats. It appears that many organisms have adapted to their living environment through complex evolutionary processes that have allowed them, over millennia, to obtain advanced properties and functionalities, producing extremely efficient materials and structures that have optimized mechanical, thermal and optical properties. THE STRENGTH OF AN EVER WIDENING RANGE OF ANTI-VIBRATION MOUNTS ELESA offers an increasingly wide range of anti-vibration mounts, to which are added the new AVR “sandwich” anti-vibration mounts. made of rubber. These anti-vibration mounts consist of two zinc-plated steel plates glued on either side of a perforated NBR rubber vibration-damping body (hardnesses 30, 50, 55, 60 and 80 Shore A). Two versions are offered with square (AVR-Q) or rectangular (AVR-R) plates and SBR rubber coating. The new AVR rubber "sandwich" vibration dampers provide effective protection against vibration and shock where resistance to compression is required and are suitable to meet the requirements of industrial air handling (HVAC) systems, for switchboards machines and presses, possible sources of vibrations which must be isolated as much as possible to avoid malfunctions and protect the health of the operator.
