“With its automated features XLRotor reduces the time spent on rotordynamic assessments so we can quickly carry out updates as a design progresses. This reduces the overall design and analysis time, enabling us to provide a very efficient and cost effective service to our clients.”

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
• Compressors, expanders, and pumps
• 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)

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 short annular seals (i.e., pump seals)
• Analysis with fully user defined bearings and structural elements
