- Abstract
- The growing demand for long-distance travel, combined with the urgent need to reduce greenhouse gas emissions, calls for more sustainable and efficient transportation systems. Among the possible options, high-speed ground transportation systems, such as the Hyperloop, have attracted significant attention. Magnetic levitation (Maglev) technologies are promising candidates for meeting the requirements of these applications, as they support the vehicle above the ground without physical contact. In particular, permanent magnet electrodynamic suspensions (PM-EDSs), which generate a repulsive force through currents induced in a fixed conductor by moving permanent magnets, offer a simple, robust, and reliable solution. However, existing PM-EDS topologies have been limited to few standard structures, with studies focusing on basic performance indicators without considering the impact of the suspension on the energy consumption or the cost of the installation. In this context, the aim of this thesis is to identify the most suitable PM-EDS topology for the magnetic levitation of high-speed ground transportation systems. To this end, analytical, numerical, and hybrid models are developed to predict the forces generated by the suspension based on its parameters. These models are validated against experimental measurements conducted on two dedicated setups. New topologies are explored using topology optimization, a method that optimizes material distribution within a defined domain. Finally, the geometrical parameters of both existing and innovative topologies are optimized, first considering only the suspension, and then integrating it into the transportation system to assess the overall cost.
