Scaled blast loading simulations on different vehicle bottom geometries
conference paper
The development of new bottom concepts for military vehicles against mine blast threats involves the consideration of two main aspects: the bottom geometry and the material used. In order to reduce costs, experimental testing of new vehicle bottom concepts often requires small-scale setups together with numerical simulations to assist the design and development process. This study first presents the validation of a numerical blast model for bare charges using experimental freefield blast data. An investigation of the reflected pressure on a flat plate shows the
importance of considering the dynamic flow for close-in blast loading since the density of the detonation products is still relatively large. The numerical blast model is applied for different vehicle bottom geometries such as a flat plate, a V-shape plate and a gull wing plate. It is shown that the gull wing provides lower load transfer closest to the charge (near the centreline), although the total impulse transfer is lowest using the V-shape.
