| Summary: | This paper extends the previous works that appears in the International
Journal of Multiphysics, Varatharajoo, Salit and Goh (2010). An approach
incorporating cohesive zone modelling technique is incorporated into an
optimized flywheel to properly simulate the stresses at the layer interfaces.
Investigation on several fiber stacking sequences are also conducted to
demonstrate the effect of fiber orientations on the overall rotor stress as
well as the interface stress behaviour. The results demonstrated that the
rotor interlaminar stresses are within the rotor materials’ ultimate strength
and that the fiber direction with a combination of 45°/-45°/0° offers the
best triple layer rotor among the few combinations selected for this
analysis. It was shown that the present approach can facilitate also further
investigation on the interface stress behaviour of rotating rotors. |
