Specific Tasks

AREA 3: Structures Static, Buckling/Stability, Thermo-Elastic Analysis

Support the generation and set-up of structural mathematical models using the finite element method for structural analysis problems for Agency funded projects, taking into account the specific objectives of such analysis, covering all structural materials applied in spacecraft and launchers. Where necessary non-linear approaches and specific solution sequences shall be applied/developed (e.g. Nastran SOL 600, Mecano, Abaqus).

Perform the analysis, evaluate critically the results and issue relevant documentation covering all analysis steps.

Support the generation and set-up of mathematical models for structural elastic stability problems for Agency funded projects, taking into account specific requirements attached to this type of analysis.

Perform stability analysis leading to the determination of buckling loads and deformations. Where necessary the post buckling behaviour shall be addressed, adequate non-linear approaches used, and where relevant specific solution sequences shall be developed.

Evaluate critically the results, and issue relevant documentation covering all analysis steps.

Support the generation and set-up of mathematical models for structural thermo-elastic stability problems for Agency funded projects, taking into account specific requirements attached to this type of analysis.

Perform the interpolation of the temperature maps as resulting from thermal analysis for their employment in finite element structural analysis.

Perform thermo-elastic analysis leading to the determination of loads and deformations, evaluate the outcome in terms of margins of safety and stability budgets, evaluate critically the results and issue relevant documentation covering all analysis steps. Where necessary non-linear approaches shall be considered and specific solution sequences shall be developed.

Evaluate critically the results and the loads and issue relevant documentation.

AREA 2: Design and Configuration

Support spacecraft and launcher configuration studies for Agency projects. This includes operating CAD tools and participation in Concurrent Design Facility (CDF) sessions at ESTEC.

Perform mass, inertia and balance calculations and relevant budget assessments.

Issue relevant documentation covering all configuration definition aspects, and where necessary shall support the configuration definition by preliminary structural analyses using FEM models.

Ensure CAD interfaces and configuration data transfer with Agency contractors via international standards.

Ensure the interface between the CAD systems and the relevant FEM tools to enable further evaluation of the structural behaviour.

Contribute to the further development of the Structures and Configuration tools deployed in the Agency, including in the CDF.

Support progress meetings and reviews in support to Agency projects.

Support the updating and maintenance of CAD and FE models databases.

Support and contribute to the establishment and maintenance of relevant Structures Engineering Standards and Handbooks.

AREA 4: Structural Dynamics Analysis and Vibration Test Data EvaluationDynamic Test Data Analysis and Correlation:

Support the preparation and execution of mechanical tests (modal survey, sine, random, acoustics, micro-vibration, shock, etc) for spacecraft & launchers of Agency projects by performing and/or reviewing analytical predictions and procedures.

Perform modal identification of the test data, evaluate critically the results and make usage of these results for updating structural finite element models.

Perform assessments of shock response data.

Take into account the specific objectives of such analyses and where necessary non-linear analyses shall be performed and specific solution sequences shall be developed.

Issue relevant documentation covering all analysis steps. Where applicable produce advanced reduced dynamic mathematical models.
