Auto-Balancing of Anisotropically Supported Rigid Rotors

Abstract

This paper presents a generalisation of investigations into single-plane auto-balancing of statically and dynamically unbalanced rigid rotors considering the influence of support anisotropy. In the analytical part conditions for existence and stability of forward whirl are derived. The question of simultaneous backward whirl compensation is answered, and two special cases of supporting are  considered. The results are confirmed by numerical  simulations. Further simulation results for the two-plane device are included.
