Abstract Based on the shock initiation of explosive—Lee-Tarver ignition and growth model,a three-dimensional numerical model was developed using the finite difference code AUTODYN to simulate the processes of jet penetrating and detonating a “sandwich” ERA(explosive reactive armor),and an explosive pressure driven flyer plate incising a jet.Aiming at three influence factors in-cluding flyer plate thickness,interlayer charge thickness and jet inclined angle,the evaluating indicators of jet disturbing efficiency were determined.By means of the orthogonal statistical test method,the parametric sensitivity of the evaluating indicators of jet disturbing efficiency was studied.Results demonstrated that jet inclined angle is the main influence factor,jet’s lateral momentum,jet tip velocity and the time of jet penetrating back plate are significantly affected by jet inclined angle,the relationship between jet inclined angle and evaluating indicators is positively correlated; flyer plate thickness is the second main influence factors, it affects all evaluating indicators evidently; interlayer charge thickness’s influence on jet tip velocity has no obvious regularity,and has also few influence on the time of jet penetrating back plate.
