摘要：

正面碰撞的安全性对车辆前期开发非常重要。为研究前排假人腿部受伤害的影响因素, 对假
人进行摆锤冲击试验。Hybrid-III 50th 男性假人安放在标定台座椅上，用5 kg 的摆锤，以2.75 m/s
速度，冲击假人左腿膝部或小腿，测量了大腿受力F、膝部位移D 、上小腿绕X、Y 轴的弯矩MX 和
MY、轴向压缩力FZ，以及胫骨指数(TI)。结果表明：当假人小腿中心与地面的夹角α 为76°值时，F、D 、
MY 发生突变。因此，为减少对小腿的伤害，在做车辆人机工程时，在大腿力容许范围内，应尽量使
小腿碰撞位置靠近膝部，并使角α 小于76°。

Abstract:

Front impact safety is important to early develop vehicles. Pendulum impacts were performed on a
dummy to investigate the influence factors to front-seated-dummy lower-leg injury. A Hybrid-III 50th male dummy
was seated on a chest calibration table. The dummy lower leg or knee was impacted by a 5-kg pendulum at 2.75
m/s. The upper-leg force F, the knee displacement D, the lower-leg-upper bending-moment MX and MY, the axial
compression FZ, and the tibia-index (TI) during impacts were measured. The results show that the α of 76° is a
special angle between the lower-leg center-line and horizontal ground, because the F, the D and MY have abrupt
changes when the impact occurres at 76°. Therefore, it will be considered that lower-leg impact-position should
be close to the knee center with the upper-leg force within an accepted range at man-machine engineering
design stage to reduce lower-leg injury. The angle α should be avoid being at the special angle of 76°.
