Occupant safety in vehicle mine protection

Personnel safety is crucial in operations where mines pose a threat, in peacekeeping and peace-enforcing operations occupant safety has a high priority. In the past five years, the TNO Defence Research Organisation participated in projects for the improvement of the mine protection of several military vehicles to increase the occupant safety. In full-scale tests, the loads on the occupants are measured using an instrumented HYBRID III 50%-tile male crash test dummy. The results of these measurements were input for injury assessment and for numerical studies with the occupant safety code MADYMO. The objective of the current research is to obtain a good understanding of the process of a mine detonation and the effects for the occupants. This analysis also provides the possibilities for the definition of load profiles that could be used for experimental research on seat and restraint systems. Second objective is to identify possibilities for structural improvements to reduce occupant loads. In full-scale experiments several solutions for improvement have already been tested more or less successfully. An overview and analysis of these solutions may help in finding new optimised systems that will reduce occupant loads. This paper presents also an overview of injury biomechanics as well as an overview of the numerical studies performed within the Vehicle Mine Protection research programme at TNO.
