IV.1.5.3 Thermo-elastic load cases
One defines also two data files corresponding to the definition of thermo-elastic load cases on
the structure. The file “temp_disc.bdf” defines four load cases in which discontinuous
temperature fields are applied to the structure. The four load cases are defined as follows:
- “TEMP_PZ_COLD” corresponds to a temperature of -100 C
on panel +Z and -50 C
on the rest of the structure.
- “TEMP_PZ_HOT” corresponds to a temperature of 120 C
on panel +Z and 70 C
on the rest of the structure.
- “TEMP_PANLAT_COLD” corresponds to a temperature of -100 C
on lateral panels and -50 C
on the rest of the structure.
- “TEMP_PANLAT_HOT” corresponds to a temperature of 120 C
on lateral panels and 70 C
on the rest of the structure.
The file “temp_grad.bdf” defines three load cases corresponding to gradients of 100
C/m
applied on the entire satellite:
- “TEMP_GRAD_X” corresponds to a gradient in direction X.
- “TEMP_GRAD_Y” corresponds to a gradient in direction Y.
- “TEMP_GRAD_Z” corresponds to a gradient in direction Z.
