摘　　要：爆炸冲击波是炸药对外作用的主要毁伤元。新型武器装备研制、爆破器材研发、防护工程设计、安全事故评估等应用领域都对近距离爆炸条件下的冲击波压力测量提出了很高的要求。压杆式冲击波反射压力测试系统具有量程大、抗干扰能力强等优点,在近距离爆炸载荷测量方面获得了大量应用。本文简要介绍了压杆式冲击波反射压力测试系统的发展历程和技术现状,重点对杆中应力波弥散效应及校正方法等进行了详细阐述,对国内多个单位及西北核技术研究所的研究进展进行了介绍,并提出了后续发展建议。The shock wave of an explosion is the main damage element of the external action of explosives.Application fields,such as new weapon development,explosive equipment development,protective engineering design,and safety accident assessment,have put forward high requirements for the close-up shock wave pressure measurement under close range explosion conditions.The pressure bar type shock wave reflected pressure measurement system has the advantages of large range,strong anti-interference ability,and has been widely used in the measurement of close-up range explosion loads.This paper briefly introduces the development history and technical status of the pressure bar type shock wave reflected pressure measurement system,with a focus on the research work of the stress wave dispersion effect and correction methods in the bar.It also introduces the research progress of many domestic institutions,including Northwest Institute of Nuclear Technology,and puts forward suggestions for future development.
