摘　　要：为解水下接触爆炸对舷侧空舱结构破坏载荷特性,该文对其测试技术进行研究。对于冲击波的破坏载荷,采用DPS(多普勒光纤探针)获取外板在冲击波作用下的速度时程,分析得到不同接触爆炸条件下冲击波破坏载荷的时空分布特性;对于爆轰产物的破坏载荷,在外板上预制破口,在内板位置放置质量块作为效应物,采用激光位移传感器测得质量块在爆轰产物作用下的位移时程,分析得到爆轰产物破坏载荷随爆距的变化规律。研究结果表明,该文提出的水下接触爆炸对舷侧空舱结构破坏载荷的测试技术是可行的,可为相关理论研究和试验测试提供技术基础。In order to study damage load characteristics on broadside cabin subjected to underwater contact explosion,the measurement technology was studied.For the shockwave damage load,the DPS was used to measure the velocity-time curve of the outside plate,then the temporal and spatial distribution characteristics of shockwave damage load by different distance was analyzed.For the detonation product damage load,a hole was precutted,and a mass block was placed at the location of the inside plate,the laser displacement sensor was used to measure the displacement-time curve of the mass block,then the variation rule with distance of detonation product load was analyzed.The results show that the measurement technology for damage load on broadside cabin is feasible,which could provide technology basis for theory and experiment research.
