采用仿真方法，分析了爆炸冲击波和破片对人体的损伤作用以及防弹衣的防护效果。结果表明，与单一爆炸冲击波相比，爆炸冲击波与破片联合作用下胸部损伤更为严重。胸骨、肋软骨和肋骨的峰值应力分别增加334.34%、170.23%和39.72%。肺侧的峰值应力降低了3.95%，变化不大。肺前、后表面的峰值应力分别增加了83.58%和409.09%。总体而言，肺损伤加重。防弹衣的加入降低了破片的损伤，胸骨和肋软骨的峰值应力分别降低了48.77%和69.78%。由于爆炸冲击波与人体背心和胸部的相互作用，加剧了爆炸冲击波对人体的损伤。肋骨的峰值应力增加了13.55%，肺前、侧和后的峰值应力分别增加了1.22%、6.51%和3.57%。
Using a simulation based method, this paper analysis the damage effect of blast wave and fragments on human body and the protective effect of bulletproof vest. The results show that compared with the single blast shock wave, the chest injury is more serious under the combined action of blast shock wave and fragments. The peak stress of sternum, costal cartilage and rib increases by 334.34%, 170.23% and 39.72%, respectively. The peak stress on the side of the lung decreases by 3.95%, with little change. The peak stress on the front and back of the lung increases by 83.58% and 409.09% respectively. Overall, the lung injury is aggravated. With the addition of the bulletproof vest, the damage caused by fragments is reduced, and the peak stress of the sternum and the costal cartilage decreases by 48.77% and 69.78%, respectively. Due to the interaction of the blast wave with the vest and the chest, the damage caused by blast wave is aggravated. The peak stress of rib increases by 13.55%, and the peak stress of lung front, side and back increases by 1.22%, 6.51% and 3.57%, respectively.
