The main component structurally analysed was the rotor as, based on previous prototypes, it is predicted to be a component highly susceptible to failure. The rotor was simulated under frictional loads transferred from the rollers that can likely initiate cracks in the rotor’s legs. However, the simulation estimated a factor of safety of 15, signifying that the rotor can withstand the frictional forces. Additionally, the maximum stress levels are at the centre of the rotor as shown in the figure below. This indicates that this area could be considered as the most likely to introduce failure, and as such should be regularly inspected during maintenance.

Furthermore, the weight of the attached components on the rotor was simulated, not only to identify if failure is possible from the weight, but also to investigate if the weight will elastically deform the rotor leg, consequently altering the position of the rollers which can then collide with the casing. The analysis concluded that the displacement due to the weight is approximately 0.04mm, which is negligible and should have insignificant effect on the roller’s position as shown in the figure below. Additionally, the factor of safety was found to be around 11, which indicates that the weight will not affect the integrity of the rotor.
