摘要/Abstract

摘要： 为了实现实验室范围内的高强度水下爆炸冲击波加载，在现有非药式水下冲击波加载装置的基础上，对加载水舱的结构进行了改进，并利用实验和仿真相结合的方法对非药式高强度水下爆炸冲击波等效加载特性进行了研究，分析了飞片及活塞的质量对加载冲击波强度和衰减时间常数的影响规律，确定了该方法所产生的高强度水下冲击波加载特性。进而利用该装置对0.5 mm厚铝合金靶板进行了水下冲击波加载实验。实验结果表明，改进后的非药式水下爆炸冲击波等效加载装置能够对目标结构进行有效的高强度水下冲击波加载。

Abstract: The structure of water chamber is modified for high strength underwater shock loading in laboratory on the basis of the non-explosive underwater shock wave loading device. The loading characteristics of the non-explosive high strength underwater equivalent shock wave are studied using the combined experimental and numerical methods. The dependences of shock wave strength and decay constant on the flyer plate and piston mass are investigated, and the expression of shock wave strength is established. The underwater shock loading experiments for 0.5 mm thick aluminium alloy target plate are carried out by using the modified device. The experimental results indicate that the improved device could effectively simulate high strength underwater shock loading.

Key words: explosion mechanics, non-explosive underwater shock wave, shock wave strength, equivalent shock loading
