What clients say:

I find XLRotor a unique and powerful rotordynamics software where its ease of use, productivity, Excel interface and automation with its new feature of Singular Value Decomposition analysis make it the BEST of all its kind. Moreover complicated and time consuming analyses can easily and efficiently be carried out in XLRotor within a very short time. The prompt technical support is outstanding. XLRotor is simply a MUST software for every engineer willing to master the rotordynamics field.

Applications

XLRotor is so powerful and fast that model size reduction is NOT required, so you get more accurate results, faster, than with any other program on the market. XLRotor is ideal for use in the design, maintenance, and evaluation and audit of a wide variety of rotating equipment, including:

  • Turbines and microturbines
  • Turbochargers and superchargers
  • Centrifugal compressors, expanders, and pumps
  • Vertical turbine pumps
  • Integrally geared compressors
  • Gyroscopes
  • Hydro, gas, and steam turbines (single and compound)
  • Motors and generators
  • Fans and blowers
  • Turboexpanders
  • Centrifuges
  • Energy storage flywheels


You can use XLRotor to perform virtually any kind of analysis on complete rotor bearing system models, including, but not limited to:

  • Damped eigenvalues and stability versus rotor speed
  • Undamped critical speeds versus support stiffness
  • Free-free undamped natural frequencies
  • Mode shapes in the form of 2 or 3 dimensional plots, with animation
  • Synchronous response to imbalance (bode plots or polar plots)
  • Complete rotor deflected shapes due to imbalance
  • Synchronous or asynchronous response to harmonic forces at either discrete frequencies or orders of shaft speed
  • Static deflection to shaft weight
  • Static deflection to mis-aligned bearings
  • Transient response of linear and nonlinear models
  • Torsional analysis of arbitrarily branched models
    • Damped eigenvalues and mode shapes
    • Linear response (e.g., engine orders)
    • Transient response (linear and nonlinear models)
    • Response to reciprocating torque harmonics due to gas and weight
    • Output of twist, velocity, torque and stress as functions of speed or crank angle

XLRotor also comes with an extensive set of bearing and seal analysis modules that can be used independently or embedded within a rotor analysis file. These modules allow you to perform functions such as:

  • Analysis of fluid film bearings including sleeve, tilting pad, partial arc and pressure dam
  • Analysis of ball bearings for stiffness, stress, and deflection
  • Analysis of cylindrical roller bearings for stiffness, stress, and deflection
  • Aerodynamic crosscoupling for axial flow stages
  • Empirical aerodynamic crosscoupling for centrifugal impellers
  • Analysis of squeeze film dampers
  • Combining bearings with compliant supports
  • Analysis of pocketed hydrostatic journal bearings (i.e., pressure fed)
  • Analysis of incompressible annular seals (i.e., pump seals)
  • Analysis of compressible flow Labyrinth seals
  • Analysis of Honeycomb seals
  • Analysis of Hole Pattern seals
  • Analysis with fully user defined bearings and structural elements
