Mobility, firepower and armor protection are three conflicting design requirements in any modern armored vehicle. There is a trade-off between each couple. In this study, we focused on the conflicting relationship between protection and mobility. We characterized mobility using four measurable vehicle dynamic quantities. We surveyed the different approaches for vehicle protection. Then, we studied the effect of each protection approach on vehicle mobility. Adding V shape plates for blast protection has been extensively used in modern armored vehicles with much success. Therefore, we dedicated a detailed study using finite element analysis on a generic V shape protection plate. The study included a parametric study on the effect of V shape angle, standoff distance and material type on the protection performance of the plate. It was concluded that sharper V angles are more efficient in protection. However the V angle is governed by vehicle ground clearance. In cases of vehicles with limited ground clearances, it was concluded that fitting a V shape with any angle can provide some blast protection without sacrificing mobility. We also concluded that lighter materials than steel can be used and still provide enough protection. Finally, it is believed that a study that considers all the aforementioned parameters and their effect on vehicle mobility will help in developing more capable armored vehicles.
