The selection of elastic elements for foundation of the rotordynamic test bed with active magnetic bearings (AMB)

In the final stage of the construction of the test bed for the investigation of the vibration behavior of rotor supported by active magnetic bearings (AMB), the elastic elements i.e. vibration isolators should be chosen. The static stiffness characteristics of two types of elastic elements are tested on tensile/compression testing machine. Both tested elastic elements provide low enough natural frequencies of test bed rigid body modes but softer element didn't have enough carrying capacity to bear total test bed mass therefore stiffer analyzed element is selected.
