This report discusses the work performed by the U.S. Army Research Laboratory ARL formerly the Ballistic Research Laboratory BRL to determine the impact of large caliber weapon recoil effects on lightweight combat vehicles. The work was motivated by concerns that the firing of such weapons could overturn the vehicle under certain conditions. A detailed engineering modelsimulation of the vehicle was used to investigate the recoil dynamics for both stationary and fire-on-the-move scenarios. The stationary scenarios consisted of canting the vehicle at various angles up to -10 deg with different weapon-to-hull offsets. Weapon firings were simulated with hull pitch and roll motions monitored. For the fire-on-the-move conditions, the vehicle was set at a nominal speed and micro-terrain profiles simulated a cross-country environment. By elevating the terrain profile under one side of the vehicle, the cant of 0 deg or -10 deg was achieved. Time history examples, as well as statistical data for three different weapon systems, are presented. The major result of the analysis was that while there exists significant hull motion due to recoil, a catastrophic event light armored vehicle LAV overturning should not occur.
