Description

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 to create a very thermally stable assembly. The thermal analysis approach will be presented as well as the mapping of temperatures to the mechanical model for static cases and also in the frequency domain.

Results and conclusions of the analysis campaign will be presented and finally some perspectives and lessons learned concerning the tools and methods will be presented.
