Abstract

[en] The main objective of this project is to update the original FEM model used for the prediction of the structural dynamic behavior of the Qualification Model of the EUI-HRI Doors mechanism that will be mounted on the Solar Orbiter Spacecraft. The purpose of this updating is to correlate the FEM model so it can represent with higher accuracy the physical model. The original FEM model of the EUI-HRI Doors was created in SAMCEF and this same software will be used to update the complete model. Modal Assurance Criteria (MAC) and other techniques based on modal parameters will be used for the model updating.Moreover, an introduction to the nonlinear behavior of this instrument will be studied through different nonlinear detection methods. Principal Component Analysis will be used based on the literature.

For this purpose, dynamic vibration data has been acquired at the Centre Spatial de Liège and it will be used for the model correlation and the nonlinear analysis. This project also intends to describe the process followed for the dynamic testing of a spacecraft instrument and how it is related to the verification and validation of the results.
