PERFORMANCE AND EFFICIENCY OF COMPOSITE SHAFTS SUPPORTED BY ACTIVE MAGNETIC BEARINGS

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.
