INPUT TAB1 Table containing: TAB1.'BASE_MODALE': Table with the real eigenmode base (table generated by VIBR with the option TBAS) If no eigenbase is given, the calculation is directly performed with the matrix The mass, stiffness, damping and gyroscopic coupling matrices can be given either reduced on an eigenmode base or not: TAB1.'MASS_PROJ': Mass matrix projected on the eigenmodes base TAB1.'MASSE': Complete mass matrix TAB1.'RIGI_PROJ': Stiffness matrix projected on the eigenmodes base TAB1.'RIGIDITE': Stiffness matrix TAB1.'AMOR_PROJ': Damping matrix projected on the eigenmodes base TAB1.'AMORTISSEMENT': Damping matrix TAB1.'KROT_PROJ': Antisymetric stiffness due to the rotating damping projected on the eigenmodes base TAB1.'KROTATIF': ntisymetric stiffness due to the rotating damping TAB1.'GYRO_PROJ': Gyroscopic coupling matrix projected on the eigenmodes base TAB1.'GYROSCOPIQUE': Gyroscopic coupling matrix The gyroscopic coupling matrix must be given for a rotating speed equal to 1 rad/s The unbalance load can be defined in 2 ways: 1- Only the real part of the unbalance load and the procedure compute the imaginary part assuming the rotating axe is the Ox axes (by default) TAB1.'FBALOURD': Unbalance load for a unitary rotation speed equal to 1 rad/s TAB1.'VROTATION': CHPO defined on the same point than the unbalance load which gives the direction of the rotating axe (CHPO component: RX RY RZ) 2- The user may give boith the real and the imaginary parts of the unbalance load (reduced or not on the eigenmode base) TAB1.'FBAR_PROJ': Real part of the unbalance load projected on the eigenmodes base TAB1.'FBAI_PROJ': Imaginary part of the unbalance load projected on the eigenmodes base TAB1.'FBALREEL': Real part of the unbalance load TAB1.'FBALIMAG': Imaginary part of the unbalance load The unbalanbce load must be given for a rotating speed equal to 1 rad/s TAB1.'REPONSE' : Table containing the points for which are saved the results (TAB1.'REPONSE').i.'POINT': TAB1.'SAUVDEFO': VRAI if the the complete deformed shaped is saved TAB1.'AFFICHAGE': VRAI if the values of the current computed frequency step are plotted during the calculation PROMEG: LISTREEL containing the rotating speed (unit rad/s) for which are calculated the response of the rotating machine to the unbalance load OUTPUT TAB1.'REPONSE' : Table containing i indices (TAB1.'REPONSE'). i .
