Effect of Bearing Misalignment on Rotor Vibration
Application ID: 68561
In this example, a rotor supported by two hydrodynamic bearings is analyzed. An eccentric disk located between the bearings induces rotor whirl. One of the bearings is misaligned with the rotor axis.
The Beam Rotor interface with Hydrodynamic Bearing interface in the Rotordynamics Module is used to simulate the coupled behavior of the rotor and bearings. The analysis is performed both with and without bearing misalignment, and the results are compared to investigate the effect of misalignment on the rotor's dynamic response.
The results include the orbit of the disk, the frequency spectrum of the rotor response at the disk location, and the pressure distributions in the bearings.
This model 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.
