.. _V2.02.123: **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. .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: Probl_me_de_r_f_rence Solution_de_r_f_rence Mod_lisation_A Mod_lisation_B Mod_lisation_C Mod_lisation_D Mod_lisation_E Mod_lisation_F Synth_se_des_r_sultats
