Abstract: Achieving a modified method of reluctance, mathematical models are developed firstly. Then considering more details in materials, reference boundaries of currents and a method of mesh regulation, a finite element model is also established. Finally reflected through an instance, the maximum error within the effective range, less than 1 N, demonstrates improvements of accuracy of these mathematical models. Compared with results of experiments, the maximum error and fluctuations from the finite element method are evidently smaller than those of mathematical models. Therefore, such mathematical models and the finite element method would be helpful to obtain the steady-state force of complex electromagnets.

Keywords: semi-active damper; proportional electromagnet; steady-state analysis; modified method of reluctance; mathematical model; finite element model.
