Research On Underwater Linear Shaped Charge Cutters

Linear shaped charge cutters is a install drug structure ,which shape is strip,and shaped aperture is embed in the bottom. After exploding, detonation wave spread abroad by vertical axis of install drug, the metal cover afoul in the center plane by higher than a kite press, come into being high speed athletic metal jet ,witch look like slice, there are some peculiarities,such as action rapid and incise ability strong. Oil wells that be disused in shallow sea are severe to affect sea-route. cannot cut off it effectively by dynamite commonly. and water affect jet a certain extent. Thus, It is central aim in this paper that how to manufacture a big linear shaped charge cutters in the water.This text introduce the basic theory of cumulative charge and study actuality of country inside and outside. Depict how to bring to bear ANSYS/LS-DYNA to simulate that linear shaped charge penetration target.and how to coach design by simulate, finally, work out shaped charge that be up to the mustard.Base the existing theory of shaped charge, penetration model, experiential formula, how to choose and design the material, nip degree, and thickness of linear shaped charge; Considering filly the infection of water to jet and the structure characteristic of oil wells be disused in shallow sea. Design linear shaped charge cutters of answer for the fact. By practice checkout, upswing, lastly finalize the design. On the side, this paper make use of hollow-center metal pellet to arrange in a creative way through practice, do facility- flexible cutter, use it to replace linear shaped charge cutters, bring to bear it to incise oil wells that be disused in shallow sea ,gain famous effect.Paper emphasize to explore a effective simulate means that linear shaped charge cutters penetrate target, and coach the design of big- linear shaped charge cutters, have reference worth to the correlative design for the future.
