摘要

为研究某小口径弹丸非侵彻条件下机体内的压力传递，采用压力动态采集系统，通过某小口径弹丸以不同撞击速度对长白猪和明胶靶标进行非侵彻防护射击试验，得到了靶内不同位置处的压力值。试验结果表明：弹丸速度越大，靶内产生的压力峰值越高，且压力峰值随距撞击点距离呈指数衰减；长白猪体内的压力衰减速度大于明胶靶标中的压力衰减速度；皮肤的吸能能力与撞击速度有很大的关系。该试验结果对伤员的救治、建立损伤标准及枪弹设计改型具有重要意义。

Abstract

To investigate the internal pressure transmission in body caused by the small caliber projectile under non-penetration, the non-penetration firing tests were conducted with different impact velocities and different protected targets including Landrace and gelatin to measure the pressure value in the targets at different locations by dynamic acquisition system of pressure. The results show that the pressure is higher when the impact velocity becomes greater, and the peak pressure decays exponentially with the distance between impact point and the measurement position, and the pressure attenuation speed in the Landrace is greater than that in the gelatin target, and the energy absorption ability of skin has great relationship with impact velocity. The test results have important significance in the wound treatment, the injury standard establishment, and the bullet design modification.
