doi:10.3969/j.issn.1000-1093.2015.04.021

Abstract

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
