“…One of the most crucial tasks in the development of such hammers is improvement of energy performance per cycle. Energy conversion issues in electromagnetic impact machines are among the most complex ones [8]- [13]. Energy conversion efficiency is intimately connected with formation of the operational cycle of electromagnetic machines.…”

The current work was designed to study the operating modes of electromagnetic impact mechanism (electromagnetic hammer) comprising idle and working stroke windings that are enclosed in magnetic conductor, and reciprocating ferromagnetic striker. Investigation was conducted by modelling in MATLAB environment and performing verification tests with different hammers. Simulation model of the hammer was derived using experimentally obtained static characteristic curves of flux linkage and thrust force for each of the windings. Results revealed that at maximum working stroke winding voltage-varying idle stroke winding voltage, the impact energy did not change, but the impact frequency varied between 0-187 bpm. At maximum idle stroke winding voltage and working stroke winding voltage ranging between 0 to maximum value, the impact energy varied between 84-360 J, the impact frequency varied between 96-187 bpm. Maximum losses over the working cycle were associated with electric losses in the hammer windings and can be reduced by reducing winding currents through increasing the striker speed. The mathematical model of the current study allowed quantifying energy parameters of the electromagnetic hammer. The impact machine cycle includes three operating modes, each determines the main energy parameters: efficiency, impact energy, and cycle time.

“…По сравнению с другими типами вибрационных приводов линейный электромагнитный привод имеет целый ряд преимуществ. Основными достоинствами электромагнитного привода являются: большой ресурс работы, высокая надежность, простая реализация независимого управления амплитудой (до 3-6 мм) и частотой колебаний (до 100 Гц), высокий КПД при работе на частоте резонанса [13][14][15].…”

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.
