Abstract: Blunt impact was conducted on thorax abdominal parts of 113 rabbits by using a pendulum impact table. The impact velocity was 6.7￣10.5 m/s. And the relative compression amount was 0.18￣0.50. Lateral thorax impact caused serious results than frontal thorax impact. Lateral thorax impact often led to ascending aorta damage, rib fracture and liver damage. Upper abdomen impact injury was more serious than that of lateral abdomen impact. And the former often led to liver damage. So particular emphasis should be laid on to protect lateral thorax during thorax impact. And to abdomen impact, upper abdomen protection should be considered firstly. Impact measure (M I ) and impact work ( W I ) can be used to estimate degrees of thorax and upper abdomen injury respectively and the value D E,50 of impact injury.
