v2.02.123 SDLL123 - Frequency of a simplified shaft line with gyroscopy

Summary:

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

In this test, it is a simple rotor model with 1 disks simply supported.

Four models are carried out:

• B modeling: POU_D_E

• D modeling: POU_D_EM

• E modeling: POU_D_TG

• F modeling: POU_D_TGM

The A and C models are not applicable for gyroscopy. These are mathematical validation tests.
