【摘要】 使用锰铜压力计和PVDF压力计对RS211炸药水下爆炸近场的冲击波压力进行了测试,通过数据处理得到了RS211炸药水中爆炸近场的压力数据。试验表明:(1)使用多个锰铜压力计和一个PVDF压力计所得到的信号会产生干扰,而使用一个锰铜压力计和多个PVDF压力计测得的信号干扰较少;(2)使用电测技术得到冲击波近场的压力数据难度较大,建议使用光学测试方法进行研究。更多还原

【Abstract】 The shock wave pressue at near-field of RS211 detonation in water were measured by manganin-gauge and PVDF-gauge.The data of pressure at near-filed was gained.The experimental results show that(1) the signal of pressure were disturbed each other when several manganin-gauge used,the signal of pressure were not disturbed each other when one manganin-gauge and several PVDF-gauge used;(2) the data of shock wave pressue at near-field can’t be obtained perfect by electronics test method only,it’s stronggest suggested using optics measued method to accomplish this works.更多还原
