The aim of this study was to understand the behavior of Eurosid rib module and its components under different impact conditions. This was achieved by impacting the single rib module at two different velocities of 7.6m/s and 10.8m/s at three impact angles of 0, +30 and -30 deg corresponding to each velocity. All tests were done using a 1.86 kg (4.1 lbs), 152 mm (6″) circular impactor on the Monterey facility (Linear impactor) and some of the tests were filmed at 5000 fps. Tests were also done with and without tuning spring to assess its contribution to the total rib response. The hydraulic damper and damper spring were dynamically tested at different velocities to obtain their individual characteristics of force-velocity and force-deflection respectively. Static force-deflection characteristics of all the four tuning springs and damper spring were also obtained. The results of single rib tests @ 0 deg were compared with the CAE models currently available in MADYMO-3D and RADIOSS.
