The relevance of the research lies in the need to improve the accuracy of dynamic calculations of electromagnetic oscillating systems used in technical systems for the generation of vibrations with a frequency of up to 100 Hz. The research considers the solution of the problem of creating an accurate dynamic single-mass oscillating system with an electromagnetic drive that characterizes the different operation modes and allows a comprehensive analysis of electromechanical processes by means of structural modeling methods. The distinctive feature of this model is the ability to take into account the nonlinearity of the magnetic circuit, leakage fluxes, properties of elastic linkages, viscous friction and sliding friction, external influence and energy losses of electrical and mechanical nature in an electromagnetic oscillating system. To solve the problem of calculating the magnetic field, the standard finite-element modeling FEMM software was used. To calculate the dynamic part of the problem, the calculation algorithm was developed that was implemented by means of structural modeling method in Matlab Simulink software environment. By the example of calculation of periodic electromechanical processes in the electromagnetic oscillating system, the possibilities of the model for a comprehensive analysis of operation processes are considered. According to the results of the research, recommendations for improving the accuracy of calculations of electromechanical processes were obtained.
