Abstract
In space engineering, a thorough thermal analysis on a spacecraft is necessary to evaluate structural stresses, and above all thermoelastic displacements (e.g. instrument pointing).
The main problem of such an analysis lies in the fact that thermal and mechanical engineers do not use the same software tools.
Thermal loadcases on structural models are all the more difficult to obtain that models become more and more complex. Interpolating temperatures by hand is now tedious and an inaccurate task. MATRA MARCONI SPACE recently developed an original tool that can automatically interpolate a 3D temperature map.
This tool, in the very near future, will make thermal and mechanical engineers work together without throwing back into questions their methodologies for solving this kind of problem.
