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.
For more details about the app, see this blog post: "Analyzing Critical Speeds with the Rotor Bearing System Simulator"
This application example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
