Abstract
Способ измерения параметров механических колебаний контролируемых объектов, заключающийся в том, что в колебательном контуре, содержащем катушку индуктивности и конденсатор, возбуждают резонансные колебания электромагнитного поля, отличающийся тем, что инерционное тело, выполненное из магнитострикционного материала, помещают в газообразную среду, возбуждают механические колебания в инерционном теле под действием приложенного к нему переменного магнитного поля, перемещают инерционное тело относительно корпуса, изменяют емкость колебательного контура, который является гальванически развязанным от измерительной схемы, а параметры механических колебаний инерционного тела относительно корпуса измеряют за счет изменения частоты резонансных колебаний электромагнитного поля колебательного контура.A method of measuring the parameters of mechanical vibrations of controlled objects, namely, that in an oscillating circuit containing an inductor and a capacitor, resonant vibrations of an electromagnetic field are excited, characterized in that the inertial body made of magnetostrictive material is placed in a gaseous medium, and mechanical vibrations are excited in inertial body under the action of an alternating magnetic field applied to it, move the inertial body relative to the body, change the capacitance ebatelnogo circuit which is electrically isolated from the measuring circuit, and the parameters of the inertial body relative to the housing of mechanical oscillations is measured by changing the resonant frequency of the electromagnetic field oscillations of the oscillatory circuit.
