Abstract
Dynamical analysis improvement and its capabilities extension are important for the complex
analysis and synthesis of the vibratory electromagnetic drive applied in engineering systems for
exciting low-frequency oscillations and vibrations. The electric drive dynamic model is based on
differential equations of the non-linear circuit electrical balance with respect to d'Alembert principle
for a mechanical system with spring linkages. Periodical electromechanical processes are
considered as an example for studying dynamical model capabilities of the transient and quasi
stationary mode fundamental analysis with structural modeling methods and facilities in Matlab
Simulink. It is established that dynamical analysis accuracy is significantly depends on reproduction
accuracy of mathematical models of mechanical characteristics of spring linkages and sliding
friction forces. The electric drive operation characteristics are obtained from the developed
dynamical model. The computer simulation results have been compared with physical experiment
data. The results of the dynamical model implementation and operation characteristics analysis can
be widely used for other types of machines and devices with reciprocated electromagnetic drives.
