Features of the Power Characteristics of the Vibration Isolators

Abstract

In this article the development of the perspective vibration protection device is described. The theory suggests the development of 3D-vibration isolator devices, which have power characteristics with zero stiffness area. A spatial vibroisolator is presented as an elastic element and stiffness compensator in-parallel of this element to obtain this specific area on power characteristic. This methodology allows us to make three-dimensional (3D) vibration isolator with electromagnetic stiffness compensator. This isolator allows to delete the vibration fluctuations in all three axes of space simultaneously. A spatial vibroisolated device consists of an elastic element and parallel 3D-electromagnetic stiffness compensator. An electromagnetic stiffness compensator is a two counter-mounted electromagnetic disks. Each disk is made as six electromagnetic or magnetic disconnected coils, and they are located two by two along three axes of space. The construction of one-dimensional vibration isolator with an electromagnetic stiffness compensator is presented in this article. Three-dimensional vibration isolator can be used in any area of mechanic, engineering, vibration dumping technique, which has a negative effect on human health and devices performance.
