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:
