AxSTREAM_Bearings

Applications of AxSTREAM® RotorDynamics include different types of rotors that can be used in machines such as steam turbines, compressors, pumps, electric motors, generators, and more. The RotorDynamics software can perform several types of analysis including Static Rotor Deflection, Lateral Critical Speeds, Critical Speed Map, Damped Unbalance Response, Stability, and Train Torsional Modal and Transient.Bearings allows users to synthesize and analyze detailed models of bearings for different configurations by performing steady-state, transient, and map analysis.

 

There are three typesof fluid film bearings currently available in AxSTREAM® Bearings

  • Plain cylindrical journal bearing
  • Fixed pad: Bearing ring is divided into several “pads” to optimize hydrodynamic forces
  • Tilting pad: Bearing is divided and hinge supported

 

The software has a flexible geometry configurator to model features such as pockets, lobes, oil supply channels, etc.

Steady-state analysis type determines the static equilibrium, and the bearing hydrodynamic characteristics, such as maximum film pressure, bearing eccentricity ratio, mimimum film thickness, and others required for bearing design.

Transient analysis considers dynamic conditions, when the bearing is oscillating around the static equilibrium positions, and conclusions about the stability of the journal bearing operation can be made.

Map analysis performs a series of steady-state analyses calculated under different rotational speeds. This analysis produces the characteristics, which are used in rotor dynamics analysis, namely stiffness and damping ratios.

Mechanical characteristics for different types of rolling-element bearings can be calculated using simplified approach in AxSTREAM® Bearing
