Simulation and experimental study on the shock response of vehicle add-on modules subjected to blast loading

Abstract

Explosion of landmines is recognized as one of the vital threat to armoured vehicles. The detonation of mines may also threaten the survivability of the occupants inside the vehicle by the high intensive blast waves transmitting from vehicle structures. Bottom add-on modules can be very useful to vehicle in blast protecting. The dynamic response of three different add-on structures under bottom explosion was analysed by simulations and experiments. The optimal structure was obtained by computational results and experimental results, and the protection mechanism was summarized based on the research.
