针对个体防护的冲击波检测评估技术

With the extensive application of new-type ammunitions and large-caliber heavy artillery, the non-contact killing mode caused by explosive shock is rapidly substituting the original direct-contact killing induced by bullets, fragments, etc. Characterized by high lethality and precision, it poses a greater threat to combatants and equipment. This study focuses on the technology of explosion shock wave detection and evaluation, especially in the field of personal protection. It reviews typical explosion shock wave test environments, such as real-explosion tests and shock-tube tests, and analyzes the pros and cons of electrical and non-electrical test measurement methods. The progress of piezoresistive, piezoelectric, and optical-fiber sensors is discussed. The trend of sensors towards miniaturization and intelligentization is emphasized, and the urgent need for new sensing technologies is proposed. This study also introduces the shock-wave signal processing and over-pressure field reconstruction technologies integrated with artificial intelligence, and investigates the application of new technologies like compressed sensing technology and deep neural network technology. In addition, the overall situation of typical foreign portable explosion shock wave sensing systems are summarized. To enhance the comprehensive protection and emergency treatment capabilities of combatants in extreme environments, the necessity of rapidly developing a portable explosion shock wave detection and evaluation system with independent intellectual property rights is discussed.
