摘　　要：为掌握爆炸冲击波引起的毁伤目标冲击振动加速度信号在距爆心不同距离上的规律，利用存储测试技术，设计研制了一种可相对独立工作的便携式结构振动遥测探测头。为了准确掌握探测头系统的动态性能，应用霍普金森杆进行了冲击加速度动态标定测试，结果表明该系统在量程范围（-5000～50000g。）内性能良好。通过现场3kg TNT实弹动爆试验，系统成功的记录了冲击振动加速度信号，测试结果对评估炸药的毁伤威力性能具有重要的参考价值。To master the regularity of the damage target vibration acceleration signals at different distances from the ground caused by explosion shock wave, a portably and relatively independent work vibration detection device is designed by using storage testing technology. In order to accurately grasp the probing tip system dynamic performance, Hopkinson bar is applied for the shock acceleration dynamic calibration test. The results show that the system is better performance within（-5 000 gn -50 000 gn ） Through in-situ test of 3 kg TNT high explosive,the system successfully records the vibration acceleration signal and test results which have important reference value for the assessment of the performance damage.
