Multidisciplinary Analysis of Electromechanical Actuator Based on FEM - Circuit Simulator Coupling

Design of an electromechanical system is multidisciplinary and so is its simulation. In this paper the three different types of co-simulation are compared and the output waveforms are presented. The co-simulation is realized between two different programs (power electronic circuit simulator - control part and finite element analysis - magnetic and mechanic model part). The simulations were realized for an electromechanical actuator fuel injection system. The output waveforms for coil current, forces, inductances and position are compared.
