전투 차량 전복 안전성 평가 및 전복 시 승무원의 거동에 대한 연구

Abstract

The wheeled armored vehicle has a high center of gravity, and it operates on unpaved and sloped roads. Therefore, this vehicle has a high risk of rollover crashes. To design the interior of the military vehicle, the crew’s safety during rollover crashes is an important factor. However, there are restrictions in designing the space and the safety devices of the vehicle. In this paper, nonlinear dynamic analysis is performed to simulate the rollover crashes and the passenger injury is assessed with an existing vehicle model. Moreover, designs of a headrest and a seat belt are proposed to reduce passenger injury. The results of passenger injury are compared with a previous design. HyperWorks and LS-DYNA are used for the finite element modeling and nonlinear dynamic analysis, respectively.
