Description

. Дл  измерени  деформаций объекта иримен ют уетрокства, содержащие тензомегрические датчики, еоедипепиые ио мостовой схеме и установлеииые на возбуждаемом объекте, электрониый генератор питани  и фильтр низкой частоты, вход которого подключен к измерительной диагонали датчика, а выход к регистратору.. To measure the deformations of the object, non-structural devices containing strain gauge sensors, an optical bridge circuit and installed on the excited object, an electronic power generator and a low-frequency filter, whose input is connected to the measuring diagonal of the sensor and the output to the recorder, are used.

Предлагаемое устройство более совершенно но сравнению с известными устройствами, так как оно обеспечивает измерение нериодическн возбуждаемых деформаций без нрцмеиени  дополнительных блоков нреобразовани  сигнала. Это достнгаетс  тем, что электронный генератор питани  св зан с возбудителем колебаний синхроннзирующей цепью.The proposed device is more completely compared with the known devices, since it provides a measurement of non-periodic excitable deformations without the need for additional signal conditioning blocks. This is due to the fact that the electronic power generator is connected to the oscillator by a synchronous circuit.

На чертеже изображена блок-схелга предлагаемого устройства.The drawing shows a block diagram of the proposed device.

Измерение деформаций объекта осуществл етс  тензометрическими датчиками /, которые установлены на 11сс/1едуемом объекте 2 и включены в мостовую схему. Мост с тензо.метричеекими датчиками питаетс  от электронного генератора 3; выход люста подключен через фильтр 4 низкой частоты к регистратору 3, в качестве которого может быть использован гальванометр или электроннглй поте}1циометр. Колебани  в исслодуемом объекте 2 возбуждаютс  от возбудител  6, который св зан синхронизирующей ценью 7 с электронным генератором 3. Прн такой схеме включени  тензометрнческие датчики получают питание с частотой равной частоте основной гармоники возбуждающей силы, вследствие чего измерительна  мостова  схема осуи1ествл ет фуикции разового детектора и выходной сигнал имеет посто нную составл ющую, позвол ющую фиксировать изл1ер емую деформацию га.тьваиометром или электронным нотенциометром без промежуточных нреобразователей.Measurement of object deformations is carried out by strain gauges /, which are mounted on 11 cc / 1 object 2 and are included in the bridge circuit. A bridge with strain-gauge sensors is powered by an electronic generator 3; lust output is connected through a low-frequency filter 4 to the recorder 3, which can be used as a galvanometer or electron sweat} 1-meter. The oscillations in object 2 being excited are caused by driver 6, which is associated with synchronizing value 7 with electronic generator 3. Such a switching circuit uses strain gauges to be powered at a frequency equal to the fundamental frequency of the driving force, as a result of which the measuring bridge detects fuzzies of the single detector and output The signal has a constant component, which makes it possible to fix the radiated deformation by means of a taviometer or an electronic notionometer without intermediate converters.
