  1. 63. Thermo-elastic test as part of ESA activity: Improvement of methodologies for thermo-elastic predictions and verification
    Benoit Laine (ESA)
    10/10/2019, 10:00
    mapping of thermal results to mechanical models and guidelines for thermo-elastic (for thermal part)

    Stability requirements of current and future ESA projects are getting ever more challenging, with thermo elastic distortion and strength playing a dominant role on the final performance. Compliance to those requirements is usually verified only through analytical models that are not correlated with regard to their validity for thermo-elastic predictions, leaving not quantified uncertainties in...

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

    This work has been performed as a follow on to the ESA R&D activity Improvement of Methodologies for Thermo-Elastic Predictions and Verification (I-METER). In the framework of this activity, a thermal test was performed at the facilities of Thales Alenia Space in Cannes, France in early 2019, using the structure of the Iridium Next platform. The objective of this test was to generate thermal...

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

    Thermo-elastic behaviour of spacecraft structures and payloads is often a critical design aspect due to the importance of dimensional stability (hence payload accuracy) and structural strength. The accuracy of thermo-elastic analysis relies to a large extent on the correct interplay between the thermal model, the structural model and the translation of the thermal results to the structural...

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

    SINAS is a tool for mapping temperatures from lumped parameter based thermal analysis to a finite element model for computing thermo-elastic responses. The most recent major version of SINAS was developed for ESA in 1998. Since then not many companies have been using the software. One of the reasons is the software was quite cumbersome to use; many steps had to be performed which all required...

  5. 22. SINAS: Benefits and points of attention
    Alexander van Oostrum (ATG Europe)

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

    The accuracy of thermal analysis relies to a large extent on the nodal discretisation and conduction calculation/definition in the thermal model. Traditional methods of conductor calculation use simplified analytical rules and can be very user intensive or require large simplifications. The work presented at ECSSMET 2018 [1]&[2] and ESTEW 2018 [3] considering thermal mapping and FEM based...
