Method of Measuring the Parameters of Mechanical Oscillations for Controlled Objects

Abstract

The paper considers a new method of measuring the parameters of mechanical oscillations for controlled objects. The inertial body, made of magnetostrictive material, is placed into gaseous environment. Under the action of alternating magnetic field applied to the inertial body, mechanical oscillations occur. The inertial body moves relative to the casing, changing the capacity of the oscillating circuit, which is electrically isolated from the measuring circuit. Parameters of mechanical oscillations of the inertial body relative to the casing are measured by changing the frequency of resonant oscillations of electromagnetic field of the oscillating circuit. The new method can be used to measure the amplitude, velocity, and acceleration of mechanical oscillations of the controlled object.
