This PhD thesis deals with the prediction of the lateral dynamics of squirrel cage laminated rotors known as HSM. The difficulty of the modeling is due to the complexity of the magnetic mass assembly, composed of a core of laminated steel held by excentric prestressed tie rods, and a squirrel cage consisting of a distribution of short-circuit rods also positioned at the periphery of the magnetic mass and connected to two short-circuit rings located at the ends of the laminated core. A finite element model of Timoshenko beams is developed that takes into account the monolithic nature of the HSM. The lateral behavior of laminated rotors is mainly governed by the bending rigidity of the stack whose constitutive properties are unknown and direc...
