| 摘要： | The beneficial effects of seat stroke on lower lumbar loads, and energy absorbing floors on lower and upper tibia loads are numerically simulated by LS-DYNA3D in an accelerative vertical loading environment. The Hybrid III 50% male dummy occupant dummy is seated in a generic seat system of a ground vehicle interior and restrained with a 5-point seatbelt system. A retractor system is attached between the back of the stroking seat and the hull to provide the desired seat stroking characteristics. The occupant lower lumbar loads and lower tibia loads are analyzed and compared for eight different retractor functions. |
