v5.03.110 SDNV110 — Solid rotor rotating around its axis, taking into account gyroscopy

Summary:

This test makes it possible to validate the calculation of the rotation modes of a solid rotor with and without gyroscopic stiffness.

It is a rotor model, supported by two bearings and rotating around its axis. This example is taken from references [1] and [2].

The results of the calculations are compared with those obtained with ANSYSÒ. The results coincide perfectly with the reference solution.
