Abstract

The aim of this work is the dynamic calculation of the necessary electromagnetic forces for positioning of the vehicle at different mass loads. Numerical calculations of magnetic fields and obtained forces are based on finite element method. Comprehensive solutions have been applied to the development of a parametric modelling. The paper defines the basic model for further modelling and the possibility to observe the behaviour of a given model using different types of materials and loads. Types of magnetic materials and their selection for particular parts of the model are explained. These results provide insight into the magnetic field, dependence of default coil current and power of the levitate part of the model. Using these results a mathematical model can be developed. State space model calculation can be utilized as a preparation for automatic regulation of the dynamics of the suspension.
