Description
Предметом изобретени вл етс виброакселерсметр с электромагнитным вибродатчиком, дифференцирующим контуром и дистанционной передачей результатов замера.The subject of the invention is a vibroaccelemeter with an electromagnetic vibration sensor, a differentiating circuit and remote transmission of measurement results.
Уже известны аналогичиого назначени виброакселерометры с усилительным блоком и заиисыо показаний прибора осциллографом.The analogous designation of vibroaccelerometers with an amplifying unit and instrument readings with an oscilloscope are already known.
Предлагаемый виброакселерометр отличаетс от известных тем, чтс в нем применен вместо осциллографа индикатор из купроксного моста Гретца и магнитоэлектрического стрелочного прибора, град ированного в единицах вибрационных ускорений, что избавл ет от применени усилительного блока и послед юидей обработки осциллограмм.The proposed vibroaccelerometer differs from the known ones in that it uses an indicator from a Gretz cuprox bridge and a magnetoelectric switch instrument, calibrated in units of vibration accelerations, instead of an oscilloscope, which eliminates the use of an amplifying unit and the subsequent processing of waveforms.
На чертеже изображена электрическа схема описываемого прибора , котора состоит из последовательно соединеиных индуктивностей вибродатчика, емкости С и сопротивлени и при соответствующем выборе этих величин, представл ет собой электродиффереицируюихи контур по току.The drawing shows the electrical circuit of the described device, which consists of a series-connected inductances of the vibration sensor, capacitance C and resistance, and with an appropriate choice of these quantities, represents the current-dissipation circuit and current.
В индуктивном датчике прибора иод действием сил вибрации создаетс напр жение, иропорциональное скоростп вибрации, прпчем ток в контуре после электрического дифференцировани , осуществл емого самим контуром, оказываетс пропорциональным ускорению замер емой вибрации.In an inductive sensor of the device, the action of the vibration forces creates a voltage proportional to the speed of vibration, and the current in the circuit after the electrical differentiation carried out by the circuit itself is proportional to the acceleration of the measured vibration.
В св зи с этим прибор отградуирсваи по ускорению, а шкала его индикатора-в единицах ускорени силы т жести.In this connection, the device is accelerated by acceleration, and its indicator scale is in units of accelerated gravity.
Датчики описываемого виброакселерометра выполнены в вг)де «узла измерени из трех датчиков, служащих дл замера компонент вибрации по трем взаимно-перпендикул риым ос м, и в случае измерений на самолете могут быть установлены в любой точке последнего, независимо от того, доступны эти точки оператору во .врем полета плиThe sensors of the described vibroaccelerometer are made in the VG de «measuring unit of three sensors used to measure the components of vibration on three mutually perpendicular axes, and in the case of measurements on an airplane, they can be installed at any point of the latter, regardless of whether these points are available. the operator during flight time
