Advanced Tools for Efficient On-Line Support of Test Campaigns

P. Deloo, M. Klein & J. Merlet

Two new tools have been developed for processing vibration test data: one for comparing responses from different tests, and one for predicting the notches in an intended excitation profile. The ‘Test Comparison’ tool allows the automatic comparison of responses in two or more tests, such as pre- and post-test low-level runs. The quality of the match is given in terms of numerical indices and a flexible, user-friendly interface permits an efficient assessment of the results. The ‘Notching Prediction’ tool computes the notches required for a given excitation profile, knowing the responses to a previous excitation profile and the maximum accelerations allowed for each sensor. The new excitation profile incorporating the possible notches is computed automatically based on all the responses selected by the user. Various options are available to customise the processing. These new tools have been used to support the recent qualification testing of the Polar Platform and XMM.
