Interest in rotary systems whose performance and efficiency are influenced
by their weight as well as guidance type has continued to grow over the
last decades. Actually, the dynamic analysis of composite shafts supported
by active magnetic bearings (AMBs) seems to be neglected by researchers
despite its effect on rotating system efficiency and performance. The novelty
of this work lies in the exploration of the impact of the new combination
of composite materials (CMs) and AMBs on the dynamic rotor behavior.
A finite element formulation was developed to establish the rotor motion
equation which was settled by Newmark coupled with Newton–Raphson
methods. Results revealed that the use of CMs and AMBs greatly impacted the
dynamic behavior of a rotary system in terms of performance, accuracy, and
efficiency. Numerical results are in good agreement with the experimental
ones.
