29. Thermo mechanical analysis of LISA instrument support structure

James Etchells

07/10/2020, 16:00

thermal design (for platforms, instruments etc.)

The presentation will cover the thermo-mechanical design and analysis of a concept for the LISA instrument support structure.

A brief introduction will be given to the LISA mission and to the main design drivers and requirements. The concept to be presented is a "thermally compensated" structure, where the different coefficients of thermal expansion (CTE ) of titanium and aluminium are used...

mapping of thermal results to mechanical models and guidelines for thermo-elastic (for thermal part)

Thermo-elastic analysis has been performed for the SXI instrument to check the compatibility with allowable alignment errors resulting from thermal cycling in orbit near to cryogenic temperatures. The presentation focuses on the napping of temperature results between ESATAN thermal and NASTRAN FEM mechanical. Various interpolation methods were investigated and their accuracy compared.The...
