Evaluation of a novel test setup to assess injury risk for standing occupants in underbelly mine/IED injury risk assessment tests
conference paper
TNO has developed a standalone standing lower leg test setup (St-Mil-LX) [1], using the Military Lower Extremity (Mil-LX), for assessing the protection level of standing positions in military vehicles against mine/Improvised Explosive Device (IED) Underbelly blast (UBB) threats. STANAG 4569, Protection Levels for Occupants of Logistic and Light Armoured Vehicles [2], requires full-scale vehicle testing with seated Anthropomorphic Test Devices (ATDs) but is lacking a requirement for standing occupants, which are common in some military vehicles. Previous trials to use the pedestrian 50th percentile Hybrid III (HIII-Ped) showed poor repeatability due to stabilising difficulties of the standing position in vehicle testing. The effective mass of the HIII-Ped on the lower leg was previously determined by comparing tests of the HIII Ped with the tests of the St-Mil-LX on the Mine Blast Simulator (MBS) [1]. Now, the response of the St-Mil-LX is further compared with the HIII-Ped in side-by-side tests in the Test Rig for Occupant Safety System (TROSS) to gain insight into the response of the St-Mil-LX in a loading scenario that has been used in the past to simulate actual vehicle responses to UBB.
