本文研究了动物胸腹部对气流吹袭的动态响应。共用了9头猪、5条狗和6只猴。实验是在发动机试车台上进行的,用来模拟从飞机上应急弹射时的气流吹袭。动压q_c的范围为47.1～81.4kPa.损伤严重性用AIS(Abbreviated Injury Scale)来定量。在这些实验中记录了胸内压和腹内压。还用电影摄影方法测量了胸部挠度。结果表明,在这样的q_c范围内,猪胸腹部损伤为AIS 4或AIS 5。猴的损伤为AIS 0到AIS 1。狗损伤的AIS值为1到3。胸部峰值挠度和胸部压缩随q_c增加而增大。动物胸部压缩达到34.9%～57.0%。大多数猪都有多处骨折,但狗和猴没有发生肋骨骨折。当动物弹射进入气流时,它们的胸内压(P_x)和腹内压(P_f)迅速升高,但P_x和P_f与q_c的相关不显著。
In this paper, we study the dynamic response of animal thorax and abdomen to the airflow. It shares 9 pigs, 5 dogs and 6 monkeys. The experiment was carried out on the engine test bench to simulate the air flow from the emergency ejection of the aircraft. Dynamic pressure q_c ranged from 47.1 to 81.4 kPa. The severity of injury was quantified using the Abbreviated Injury Scale (AIS). Thoracic pressure and intra-abdominal pressure were recorded in these experiments. The chest deflection was also measured using a cinematographic method. The results showed that in this q_c range, pig thorax abdomen injury AIS 4 or AIS 5. Monkey damage is AIS 0 to AIS 1. Dog lesions have an AIS value of 1 to 3. Chest peak deflection and chest compression increases with increasing q_c. Animal chest compression reached 34.9% ~ 57.0%. Most pigs have multiple fractures, but there are no rib fractures in dogs and monkeys. When the animals were ejected into the air stream, their intrathoracic pressure (P_x) and intra-abdominal pressure (P_f) increased rapidly, but the correlation between P_x and P_f and q_c was not significant.
