What is Hyperloop?

Hyperloop is a futuristic train transportation concept which functions on the principle of magnetic levitation, where arrays of magnets, known as Halbach arrays are used to generate lift and thrust for the pod.

How COMSOL Multiphysics^® Was Utilised?

COMSOL Multiphysics^® was used to aid the Strathclyde Hyperloop university team in designing our pod, specifically the propulsion and levitation systems. The software was used to simulate our Halbach Arrays with their magnet pole configurations and to determine the forces obtained as well as the heat generated, magnetic field strength and allowing us to determine how to insulate the rest of the pod from the magnetic field.

Many Simulations were carried out in order for us to design a working pod that was entered into the SpaceX Hyperloop competition and reached the finals of the competition.

Modules Used

In the simulations carried out, the AC/DC and Heat Transfer modules were used. The physics interfaces utilized, consisted of Magnetic Fields, Rotating Machinery, Magnetic in 2D and 3D and the Electromagnetic Heating Multiphysics coupling. Using these Modules and physics interfaces it was possible to determine many key factors influencing the design of our pod. The magnetic field strength as well as the lift and drag of each Halbach array was calculated at various speeds and rpms as it rotated over the test track, the heat and current induced in the track by each array configuration was also determined. The shielding thickness of the pod was also chosen based on COMSOL Multiphysics^® simulations as it would be required in order to insulate the pod and electronics from the magnetic fields.

Various other simulations were carried out in order to further refine the design of our pod to make the design acceptable for SpaceX.
