SCIENTIFIC APPROACHES TO THE DEVELOPMENT OF COMPOSITES MATERIALS FOR REDUCING VIBRATION AND NOISE IN PRODUCTION

Abstract

Goal. Scientific approaches to the development of composite materials for noise and vibration reduction in the workplace and evaluation of their effectiveness. Methodology. Сomplex of scientific methods for assessing the impact of environmental factors, such as noise and vibration, on the worker was used for the research. Сomparative evaluation of the effectiveness of the developed composite materials with the existing ones was carried out in terms of their ability to reduce noise and vibration at the worker's workplace. Results. New composite materials with an extended spectrum of action have been developed. Their effectiveness in laboratory and production conditions was evaluated. Their effectiveness was evaluated at those workplaces where an increased level of noise and vibration is registered, a comparative analysis of the new vibration-absorbing materials developed by the authors with those existing in laboratory and production conditions was carried out.Conducted studies have shown that «Vibroshtil» and «Vibroshtilmaxi» vibration-absorbing materials are characterized by a higher level of sound absorption compared to both domestic and materials of the same purpose produced in other countries, and are proposed for implementation in production, railway transport and the subway. Conducted studies have shown that «Vibroshtil» and «Vibroshtilmaxi» vibration-absorbing materials are characterized by the higher level of sound absorption compared to both domestic and materials of the same purpose produced in other countries, and are proposed for implementation in production, railway transport and the subway. The comparative evaluation made it possible to prove the effectiveness of the developed composite vibration-absorbing materials for the correction and reduction of noise and vibration levels in workplaces. The results were achieved due to the optimal selection of ingredients of composite materials and their ratio. Scientific novelty. The effectiveness of new composite materials «Vibrostil» and «Vibrostilmax» for reducing noise and vibration levels at workplaces was developed and evaluated, and their effectiveness was evaluated in order to prevent the risk of workers suffering from vibration sickness. Practical significance. The introduction of developed vibration-absorbing materials will reduce the level of noise and vibration in the workplace and reduce the risk of workers suffering from vibration sickness.
