Investigation of dynamic response of a mannequin in a vehicle exposed to land mine blast

Abstract

Explosive devices are frequently used in asymmetric combats. They severely threatens not only the armored vehicles, but also occupants. After detonation of high explosive, blast loads are transferred through shock waves and they hit the vehicle hull in a few milliseconds, which might potentially cause serious injuries on the members of occupants. Anthropomorphic test devices (ATDs) allow for evaluating the survivability of occupants in armored vehicles subjected to landmine blast in accordance with associated injury criteria standards. This study examines the emerging role of numerical simulations in the context of survivability of combat vehicles in modern warfare. The purpose of this investigation has been to compare the performance of Hybrid-III 50th percentile ATD in numerical simulation with that of full scale blast test. Force and acceleration time variations were collected from Hybrid-III dummy in blast test. Those data were then compared with numerical simulation model. Results show that the numerical simulation results are in agreement with those obtained from experiments.
