In the article the development and use of controlled electromagnetic vibration drives used in the field of intensive vibration technologies are considered. Method is proposed for adjustment of amplitude and frequency of vibration of working element of vibrating screen, which improves efficiency of cutting, its dynamic and energy indices. By solving the differential equations of the system, its main characteristics, which can be used in the calculation and design of electromagnets, are determined. For experimental research, a vibrator was developed with a drive from a two-stroke electromagnetic exciter. Based on the results of the studies, it was established that the adjustment of the near-resonance mode when the load changes can always be provided by changing the frequency of the thyristor converter voltage pulses. Optimal combinations of amplitudes and oscillation frequencies of the developed vibration sieve are determined.

The research performed is actual because it is necessary to improve methods of calculations of rapid dynamic processes in electrical units. The object of research is the construction of a two-mass technological vibration unit with electromagnetic excitation. The subject of research is the method of calculation based on the created simulation model of the vibration unit dynamic cha-racteristics in transient and stationary modes with respect to a form and frequency of the source voltage. The mathematical model is based on non-linear differential equations of the electrical and mechanical balance. The main objective of research is the development of a simulation model of a two-mass technological vibration unit with electromagnetic excitation using modern methods of computer simulation. The example of the numerical implementation of the mathematical model by structural modeling methods in the Matlab Simulink is considered and the computer model of the electromagnetic vibration unit is created. The examples of the calculation of dynamical cha-racteristics of electromagnetic vibration unit for the analysis of electromechanical processes in transient and stationary modes are presented. Some of calculated values of integral indicators describing conversion processes of electric energy consumed from a power supply are given. The proposed simulation model of a technological vibration unit can be used to calculate rapid dyna-mic processes in different modes to provide a rational choice of vibration unit parameters when it is designed. The model is also useful for the analysis and synthesis of automatic systems to control the supplied voltage amplitude, frequency and form. The results of the research can be of particular interest to specialists in the area of machine strength dynamics and vibration protection.

Study shake the phenomena in the electromechanical systems (EMS) are presented by permanent interest for the wide circle of researchers. The most effective source of vibrations in many cases is an electromagnetic causative vibration exciters (EMCV) in that there is transformation of electric power to energy of mechanical vibrations, that is related to the change of inductance. Electromagnetic vibration exciters have a number of significant advantages over other types of exciters. Due to the absence of rubbing parts they have high reliability and durability. They allow you to smoothly adjust the amplitude of vibrations over a wide range. EMCV are easy to integrate into production lines, they have easy maintenance, low operating costs and extensive automation capabilities. This phenomenon presents interest at development of electromechanics devices for intensive vibrotechnologies. Especially development guided on frequency of resonant EMCV promotes the economy of consumption of electric power and productivity of vibrotechnique. To the article the results of theoretical and experimental researches are driven on the increase of energy efficiency of EMCV and determination of output-input ratio. It is shown that losses of electric power in EMS with EMCV related to the origin of permanent constituents and ultra-harmonics of current, choice of magnetic chain and dynamic.
