The Korean light tactical vehicle (KLTV) is developed to meet the demands for a new military vehicle that fulfills certain conditions, such as multi-purpose, high mobility and survivability. Double-wishbone independent suspension is developed to improve the ride and handling performance and maximize the off-road driving performance of the new tactical vehicle. In particular, the KLTV is equipped with front and rear lifting provisions that support the vehicle safely during airlift operations. In this paper, a comprehensive analytical method to evaluate the structural safety of these components is presented. First, a vehicle dynamic model of the KLTV and a test rig for airlift simulation are developed using MSC.ADAMS/Car. Second, a finite element model of airlift kits, which are newly installed in the KLTV, is constructed. Third, stress analyses on vertical load conditions, MIL-STD-209K, and helicopter flight speeds are performed using ABAQUS. Finally, a dummy apparatus test and an actual vehicle test are conducted to verify the suitability of the airlift equipment for the KLTV. The computational method presented herein will provide useful information on the structural safety of airlift equipment during the early stages of a military-vehicle-designing process.
