IV.1.5.1 Acceleration unit loads on entire structure

One defines two data files corresponding to unit accelerations applied to the entire structure. These data files correspond to the static and thermo-elastic versions of the model respectively. On the static model, the corresponding load case names are:

• “LAUNCH_ONE_MS2_X” for a unit acceleration in direction X.
• “LAUNCH_ONE_MS2_Y” for a unit acceleration in direction Y.
• “LAUNCH_ONE_MS2_Z” for a unit acceleration in direction Z.

These load cases are defined in file “unit_xyz.bdf”. Correspondingly, one defines unit load cases on the thermo-elastic version of the model in file “orbit_unit_xyz.bdf”:

• “ORBIT_ONE_MS2_X” for a unit acceleration in direction X.
• “ORBIT_ONE_MS2_Y” for a unit acceleration in direction Y.
• “ORBIT_ONE_MS2_Z” for a unit acceleration in direction Z.
