The Concept of Vibration Protection and an Overview of the Global Market of Vibration Protection Materials

Due to the development of modern technologies, the number of sources initiating vibrations and noises has significantly increased. A variety of techniques are used to eliminate the negative impact of extraneous noise and vibrations. The article presents the concept of vibration protection, the options and mechanism for selecting coatings, and an overview of the global market for vibration-proof materials. The most common methods of vibration protection are vibration isolation and vibration damping, implemented by using materials with appropriate properties. Vibration isolation of vehicles is carried out by surface treatment with special mastics or coating with substrates as well as with the usage of hydraulic vibration supports. To minimize the impact of vibrations on buildings and structures, special fastenings and suspensions, vibration isolators, supports, soft rolled and sheet materials are used. For vibration isolation of machine tools and precision equipment, separate supports, a layer of elastic material placed between the machine and the foundation, a floating floor on an elastic base are used. The article presents a brief analysis of metal, rubber and rubber-metal vibration isolation supports in the budget, medium and premium price segments. Vibration damping is performed using special plates, which are available on the market in the form of rolled materials and multilayer plates. Vibration-absorbing composite polymer coatings based on thermosetting polymers have become widespread. The industry of Russia and foreign countries has established the production of vibration-absorbing reinforced sheet materials. Russian scientists are also actively developing new types of coatings: gradient polymer composite materials, thermoplastic extrusion films, laminated fiberglass polymers, etc.
