ABSTRACT

Due to the severity of forces exerted during an IED blast, ground vehicles undergo multiple sub-events including local structural deformation of the floor, blast-off, free flight and slam-down (including rollover). Simulation of the entire blast event is computationally intensive due to the high fidelity level of the model and the long duration of the event. The purpose of this project was to develop a computationally-efficient, reduced order model to simulate the blast event in one single simulation, to be used for rapid evaluation of military ground vehicles. Models were developed using MADYMO’s rigid body and finite element integration techniques. Different methodologies used in MADYMO simulations, their performance results and comparisons are presented. A Hybrid III 50th Percentile male ATD model, enhanced for use in vertical loading conditions, was developed and validated to drop tower tests.
