机械传感器测量炸药近爆区爆炸破坏作用实验研究

通过机械传感器对炸药近爆区爆炸波破坏作用研究,引进爆炸波能量面密度的概念,结果表明,机械传感器可以有效地测量近爆区爆炸波破坏强度,爆炸波能量面密度可以作为近爆区爆炸波破坏作用评定标准;比较机械传感器与压电传感器测量结果,二者在距爆心较远区数值吻合较好。

Abstract : 　The article introduces a concept of an explosive wave energy surface density by the study of mechanical sen2 sor for measuring explosive damage in the near field. The result shows that the sensor can measure explosive breaking strength efficiently ; moreover , the sensor can be regarded as an explosive wave damage criterion for evaluation in the near
field. At the same time , mechanical sensor is compared with a piezoelectricity sensor , and the results of measurement coin2 cide in relatively further field , which shows that mechanical sensor can be used to guide project in practice.
