Abstract

This invention relates to a vibration technique. The purpose of the invention is to increase the development of the No. 1x efforts and reduce nonlinear distortion. The vibration exciter, comprising a housing, a magnetic core with annular working gaps placed in the housing, and fixed in the housing by means of annular membranes, is equipped with two diamagnetic disks, power coils are rigidly attached to the KOTOpttM, and a detachable diamagnetic sleeve secured to the magnetic wiring and a sub-magnet element. .

Description

if

The invention relates to a vibration vibration technique and can be used, for example, in active protection systems.

The aim of the invention is to increase the developed efforts and reduce non-linear distortions,

The drawing shows the design of the proposed device,

The vibration exciter contains a magneto wire 1, consists of core 2 and outer cylinder 3, element 4 is magnetised, unequal elastic elements in the form of annular membranes 5, and Sj. Fastened in centers with core 2 and along the contour introduced with a body 6, consists of a lateral cylindrical wall 7, a cover 8 and a base with a mounting flange 9,

sipovye coils 10 and U, placed in annular gaps 11, and 11 magiitovod 1, two diamagnetic disks 12, and 122, a fastening element and an outer cylinder, made in the form of a detachable diamagnetic sleeve 13, placed in annular grooves of the core 2 and cylinder 3 and rigidly fastened to them, with eton diamagnetic disks 12 and 12 are installed between the end surfaces of the lateral cylindrical wall 7 and, respectively, the lid 8 and the base 9, and the internal forces of the diamagnetic disks 2 and 12j are attached New coils Yu and 10, the inner diameter of the diamagnetic sleeve 13 being smaller, and the outer diameter being greater, respectively, of the inner and outer diameters of the annular gaps of the magnetic conductor 1, whose height exceeds the height of the power coils 10 and 10

The device works as follows.

When w / w, voltage applied to sip coils 10 | and the South excites oscillations of the reactive part of the exciter comprising core 2 and the outer cylinder 3 fastened to it, biasing element 4 and diamagnetic plug 13. At the same time, the magnetic flux is concentrated in the annular working gaps And, and 11 of the magnetic circuit 1, and the weight of the reactive part of the vibrator increases significantly , which leads to an increase in the developed efforts by 1.5 - 2 times and a decrease in nonlinear distortion.
