Rotors Connected by a Spline Coupling
Application ID: 35931
In this example, learn how to model two rotors connected by a spline coupling. The first rotor is a fixed cantilevered rotor and the second rotor is supported. The model assumes that only translational motion is coupled between the rotors through the coupling, while the rotations of both rotors are uncoupled.
The tutorial demonstrates how to perform an eigenfrequency analysis at different speeds of the rotor, where the gyroscopic effects in the rotor stiffen the forward modes and soften the backward modes. The simulation results are illustrated in a Campbell plot and the critical speeds are compared and found close to those obtained in references.
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.
