摘要：

The absorbers of energy are more and more studied to develop the passive safety of a vehicle. So, it is import:ant to test them with a well-adapted testing bench. The block-bar seems to be particularly interesting because it allows a long duration of impact. But the investigated results are highly spoiled by some noise. To process the signals well, we have to find the origin of the perturbations: one is induced by the eigenmodes of the block-bar which are excited; the second is due to the scheme of reconstruction of the signals. Then, we process the signals to obtain their trend. The results obtained by a numerical 'experiment' confirm our conclusions. (C) 2001 Academic Press.
