Bearing Analysis

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)


life estimates

Fluid Films



squeeze films

annular seals

most liquids and gases


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.
