The article presents a numerical model of a coupled electro-magneto-mechanical system - an electromagnet exposed to vibration of a yoke. Operation of a multi-physical (an electro-magneto-mechanical) model is simulated under different working and excitation conditions and a response of the system is analyzed. Simscape, a tool of MATLAB programming environment, is used for numerical analysis of the problem. It is shown, that there exists a combination of operation parameters, which can lead to a substantial attenuation ot the yoke vibration. Furthermore, there exists a critical magnitude of the current, which corresponds to a permanent attraction of the yoke to the electromagnet. An analysis of electormagnet‘s initialization shows an induction of high voltages in electric circuit, which can damage the electromagnet and need to be avoided by a proper choice of parameters. and Obsahuje seznam literatury
