Abstract
The commonly employed “indifferent equilibrium” postulate is rejected as internally inconsistent, and the dynamics problem is solved by using a system of discrete masses with fixed unbalances arbitrary in magnitude and direction. A method is presented for the calculation of bearing reaction as a function of machine speed including the effect of turbulent-flow damping at disk masses, so-called gyroscopic moments, and bearing oil-film and support flexibility. The calculation is particularly adapted to a digital-computer program employing successive multiplication of 5 × 5 matrices with complex elements.
