v2.02.124 SDLL124 - Rotating beam with 3 disks subjected to gyroscopy

Summary:

This test makes it possible to validate the calculation of the rotation modes of a rotating shaft system with the CALC_MODE_ROTATION command.

In this test, it is a simple rotor model with 3 disks, supported by hydrodynamic bearings. This example is taken from the reference [bib1].

The reference results are the result of a calculation with ROTORINSA, [bib2], finite element software designed to predict the dynamic behavior of rotors under bending.

A good agreement is observed between the Code_Aster results and the reference solution.
