INVESTIGATION OF DYNAMIC CHARACTERISTICS OF NEW MAGNETO-ELASTIC TRANSDUCERS OF MECHANICAL QUANTITIES

In the article examines the dynamic characteristics of new magnetically elastic converters of mechanical quantities by the method of parametric structural circuits. It is shown that the developed differential transformer magneto–elastic converters of power parameters in automatic monitoring and control systems act as a real differentiating link without statics, and magneto-elastic converters of motion parameters act as a whole in the form of sequentially connected oscillatory and real differentiating links. It has been established that the duration of the transient process in magnetoelastic converters of power parameters is determined by the parameters (magnetic capacitance and active magnetic resistance) of the magnetic circuit, and the duration of the transient process in magnetoelastic converters of motion parameters is mainly determined by the parameters (active resistance, inductance and capacitance) of the mechanical circuit. It is revealed that the duration of the transition process of magnetically elastic motion parameter converters is on average eight times longer than the duration of the transition process of magnetically elastic force parameter converters.
