2006-1-16 RE: calculating shaft critical speed by hand. electricpete (Electrical) 13 Jan 06 14:43. For a very stiff rotor, you can approximate the critical speed as (1/ (2PI)) * sqrt (2*k/M) where k is bearing stiffness per bearing and M is rotor mass. Unfortunately, to the extent that the rotor flexes, this formulation also overestimates the critical ...
