Large rotating devices, such as paper machine rolls and electric motors, suffer from resonance vibrations due to differences in the stiffness of their mounting points. This study focused on the development of a biaxial support stiffness adjustment system for a rotor mount, which was designed to independently vary the support stiffness in both horizontal and vertical directions. This adjustment was accomplished by introducing a device that varies the effective length of two cantilever beams attached to a rotor mount to modify the support stiffnesses of the mount. Experimental results confirmed a relationship between the adjusted length of each beam and the first mode natural frequency of the system in both directions, proving the effectiveness of the solution. The system could serve as a useful tool in testing benches to simulate various rotor support stiffnesses and validates the usefulness of the concept in practical applications in optimizing rotor dynamics and improving rotor system performance.
