(54) ЭЛЕКТРОДИНАМИЧЕСКИЙ ВИБРАТОР(54) ELECTRODYNAMIC VIBRATOR

1one

Изобретение относитс  к виброиспытани м и может быть использовано при разработке низкочастотных злектродннамических вибраторов, служащих дп  определени  собственных частот испытуемых объектов и дл  калибровки вибропреобразователей .The invention relates to vibration tests and can be used in the development of low-frequency electrodynamic vibrators serving in determining the natural frequencies of test objects and for calibrating vibrator transducers.

Известен злектродинамический вибратор, включающий магнитопровод с катушкой подмагничивани  и рабоч й катушкой и систему центрировани , представл ющую собой гидростатическую ionopy с ограничителем поперечных смещений платформы 11.A electrodynamic vibrator is known, including a magnetic core with a bias coil and a working coil, and a centering system, which is a hydrostatic ionopy with a transverse displacement limiter of the platform 11.

Недостатком известного устройства  вл етс  нелинейность воспроизводимых колебаний из-за вли ни  упругих зле ментов системы центрировани , что сказьшаетс  иа точности стределени  собственной частоты колебаний испытуемого объекта.A disadvantage of the known device is the nonlinearity of reproducible oscillations due to the influence of the elastic evil elements of the centering system, which affects the accuracy of the natural frequency of oscillations of the test object.

Наиболее близким по технической сущности к предлагаемому  вл етс)|. злектродинамический вибратор, содержащий магнитопровод с катушкой подмагничивани  и рабочей катушкой, распол -вой в зазоре магнитопровода, Центральный прис динительный шток и систему центрировани  рабочей катушки, вьшолнеиную на азростатнческих The closest in technical essence to the proposed is) |. Electrodynamic vibrator containing a magnetic core with a bias coil and a working coil, located in the gap of the magnetic circuit, a central advancing rod and a system for centering the working coil, complete with waveguide

опорах, включающую направл юидае с каналами воздушной смазки и обоймы, жестко св занные с рабочей катушкой и центральным пртсоединительным штоком, при зтом опоры выполнены в виде двух аэростатических подшип1шков квадратного сечени , один из которых размещен под углом i 45° относительно другого 2.The supports, including a guide with air lubrication channels and sleeves, are rigidly connected to the working coil and the central connecting rod, while the supports are made in the form of two aerostatic bearings of square section, one of which is placed at an angle of 45 ° relative to the other 2.

Недостатком известного вибратора  вл етс  незначительна  углова  жесткость системы| центрировани  вследствие расположени  подшипников на направл юших, проход щих вдоль центральной оси вибратора, в результате чего нарушаетс  точность воспроизведени  колебаний.The disadvantage of the known vibrator is the slight angular rigidity of the system | centering due to the location of the bearings on the directions of the ones passing along the central axis of the vibrator, as a result of which the reproduction accuracy of the oscillations is disturbed.

Цель изобретени  - повьппение точности {воспроизведени  колебаний за счет увеличени  угловой жесткости системы центртроваш .The purpose of the invention is to increase the accuracy of {reproducing oscillations by increasing the angular rigidity of the center-turn system.

Поставленна  цель достигаетс  за счет того, что в известном вибраторе направл ющие азростатических опор расположены на одинаковых рассто ни х от оси вибратора, параллельно ей и жестко закреплены на магнитопроводе. This goal is achieved due to the fact that, in a known vibrator, the guides of azostatic supports are located at the same distance from the axis of the vibrator, parallel to it and rigidly fixed on the magnetic core.

На чертеже представлено предлагаемое устройство .The drawing shows the proposed device.
