Rotor Bearing System Simulator

Application ID: 45541

This app demonstrates the following:

  • Navigation system using toggle buttons in the ribbon and Back/Forward buttons in the settings window
  • Selecting predefined or user-defined materials
  • Using a table for input of geometry objects

The app simulates a rotor bearing system consisting of disks and bearings mounted on a rotating shaft. An eigenfrequency analysis is performed for a range of angular speeds, to identify critical speeds of the system.

An app of this kind is useful at an early design stage where design modifications can be made to move critical speeds away from the operating speed of the system.

Results include whirl modes, a Campbell plot, and a list of critical speeds.

This application example illustrates applications of this type that would nominally be built using the following products:
