Радіовимірювальний прилад визначення амплітуди ультразвукового випромінювача

Abstract

In the master's qualification work the analysis of the publications devoted to theoretical and experimental research of radio measuring methods and means of definition of amplitude of fluctuations of the ultrasonic radiator is carried out. The analytical method of calculation of integral parameters of the system "measuring primary transducer - cylindrical object of control" in Cartesian and cylindrical coordinate systems based on the principle of superposition and Greenberg's method is scientifically investigated. A mathematical model of the system "measuring primary converter - cylindrical object of control" is developed, which allows to calculate the full impedance of the system for both rectangular and round inductors of measuring primary converter and cylindrical object of control, taking into account the finiteness of the object of control , electromagnetic parameters of the material of the object of control. In the practical plan experimental researches are carried out and principles of realization of the offered method of mathematical calculation of integral parameters of system "measuring primary converter - cylindrical object of control" are developed. A computer program has been developed that allows to calculate the integral parameters of the system "measuring primary transducer - cylindrical object of control" for rectangular and round coils. A method for measuring the amplitude of ultrasonic mechanical vibrations of the object of control has been developed. The fifth section describes the recommendations for occupational safety and health when working with this device. The section of labor protection considered such issues of labor protection and safety in emergency situations as technical solutions for occupational health and industrial sanitation, determination of attenuation of ultrasound shielding, technical solutions for industrial and fire safety.
