The paper outlines a beam non linear formulation capable of describing the three dimensional behaviours of composite blades and usable in an optimization system. The response couplings are all taken into account by the method used to characterize the beam cross section. Such a linear constitutive law represents the starting point for an updated Lagrangian formulation of the beam elastic problem...

A bearingless flux-switching permanent magnet memory machine (BFSPMMM) is proposed, which demonstrates the advantages of good suspension performance and wide-ranging speed regulation. The bias magnetic field radial force generated by motor provided magnet, can flexibly decide whether to adopt a single-phase or two-phase mode conduction according needs levitation in X- Y-directions, so as ensure...

The special rotor structure of the axial PM bearingless flywheel machine(APM-BFM) makes its critical speed more easily affected at high speed, but there are few studies on dynamics, especially under load conditions. In paper, model analysis study APM-BFM is carried out. First, mechanism used to explain and system analyzed in conjunction with experimental prototype; centroid deviates from center...
