Study Of Fuze Resisting High-load Technology In Embedded Tandem Sub-Munitions

Based on theoretical analysis, numerical simulation and experimental verification, the fuse misfire phenomena is study in this thesis, which is formed by structural deformation or disintegration occurring in embedded tandem sub-munitions penetrating the armor plate.In this paper, the main research contents and results are as follows:(1) Via the choice for the parameters of bomb, fuse and material using in armor plate, the analysis mode was build for the course when embedded tandem sub-munitions penetrating the armor steel target, which was also be verified by the simulation experiment.(2) The buffer mechanism in penetrating process is analysis when equipped the buffer washer in embedded tandem sub-munitions. By using ANSYS/LS-DYNA simulation software, on the same velocity condition, the different buffer effect result using the variation material gasket cushioning at the same thickness is analyzed.(3) The epoxy resin is used as a potting material through the contrasting of different potting technology as well as different common potting objects. The model was established for ciecuit which is encapsulated with potting material by using ANSYS/LS-DYNA software. The force status of the circuit is simulating analysis for the course when in the penetrating process.The design scheme of fuze resisting high g-load is fulfilled by adding whole buffer system through the theoretical analysis, numerical simulation and experimental verification, which is used in embedded tandem sub-munitions. Not only the weak link of fuze scheme is analyzed, but also performance improvement by change the process potting in the circuit. As the simulation and experiment results showing, the scheme can make the fuze with structural integrity in the course of penetrating the armor steel target, and also improve the reliability and firing rate of the fuze.
