Speed is determined, have studied different structure linear cavity effect cutter under the detonation mode of end, it was demonstrated that cavity liner shape
Shape and material are to the speed of jet stream and are formed with larger impact.Brown combines the jet energy transmission under the different height of burst, jet stream
Diverging essence and design parameter relationship propose end detonation linear cavity effect cutter Optimum Theory.Yi Jiankun is directed to
LSC bad reason of initiation ends cutting effect under the detonation mode of end is analyzed, and it is general to be put forward for the first time " end effect "
It reads, but its processing that detonation wave at explosive free face is considered as sliding detonation wave is excessively rough, furthermore he is directed to terminal point
Detonation and face detonation have carried out numerical simulation in jet stability section to cutter, propose and transmit certain distance rear end in detonation
The influence of point initiation and end face detonation to jet stream reaches unanimity, but lacks rigorous demonstration.Linear cavity effect cutter is at home

The cutting of " Bohai Sea two " drilling platforms alloy spud leg.1988, the cutting cartridge suitable for oil pipe cutting was succeeded in developing, and was cut
Principle is equally the penetration effect with energy-gathering jetting.In addition, Yan Shilong et al. to jet cutter underwater demolition cutting steel plate into
Experimental study is gone, using most descending square law to analyze the factor for influencing depth of cut, and proposing should be according to cutting
It is required that from process safety, cutting effect and economic benefit etc. complex optimum cutter parameter.Li Xinhui etc. is to ring-type
The submerged performance of cavity blasting cutter is studied, and carried out bursting property test under water, it was demonstrated that poly- using V-type
Energy cavity liner can achieve the purpose that cutting or damaged underwater flexible chain.
Although having much for the research of linear cavity effect cutter, most of experiments are all to carry out in air medium
, underwater demolition technical research is relatively weak, is concentrated mainly on the fields such as numerical simulation, test and engineer application, underwater demolition
Mode is still based on underwater contact demolition and non-contact demolition.Since aqueous medium influences very big, underwater demolition to melt injection
Test is not only difficult to carry out but also success rate is very low, more and more the problem of being difficult to testing and verification start by computer means into
Row numerical simulation studies water-bed shock wave wave propagation, fluid structurecoupling problem etc. to carry out cavity liner and explosive waterproof measure
While guarantee penetration effect.
