In addition to forced response predictions (bearing
loads and shaft deflections), we can analyze and include the following
types of bearings in a system model:
Rolling
element bearings
(ball and roller)
quasi-static analysis (deflection vs load)
transient
life estimates
Fluid
Films
hydrodynamic
hydrostatic
squeeze
films
annular
seals
most
liquids and gases
Magnetic
full control circuit model
frequency-dependent sensors, controllers, amplifiers, actuators
coupled
to structural dynamics for combined system response
With most rotor-bearing
systems, supports play a significant factor in both natural
frequency and forced response analyses. We calculate the dynamic
coefficients and also
consider sensitivity.
