Electromagnetic acceleration of ferromagnetic bodies

Original language description

Electromagnetic acceleration of ferromagnetic bodies is analyzed as a coupled electromagnetic-thermal problem. The mathematical model of the process consists of two ordinary differential equations describing the time evolution of the current in the fieldcircuit and motion of the accelerated body and two partial differential equations describing the distribution of nonstationary electromagnetic and temperature fields. The model is then solved numerically by a combination of the finite element method (FEM) and time integration of the circuit equations. The methodology is illustrated on a classical electromagnetic actuator with ferromagnetic plunger. Attention is paid mainly to its dynamic behavior and temperature rise of its structural parts.
