In the METIS project context (Multiphysics Exploration Technology Integrated System), TOTAL R&D is developing seismic receivers, called DART (Downfall Air Receiver Technology). DARTs, dropped from the air, are used to perform seismic surveys in hardly accessible locations, such as tropical forests.
The purpose of this study is to realise a dynamic mechanical analysis of the DART free fall and to then evaluate the effect of several parameters such as the ground type, the centre of gravity location and the plastic materials, on the calculated constraints.
