DESIGN, SIMULATION AND EXPERIMENT OF PROTECTIVE STRUCTURE FOR ANTI-HIGH OVERLOAD FUZE
View through CrossRef
The fuze withstands high overload in the electromagnetic launch. The design of an antielectromagnetic launch overload structure draws much attention in the field of the fuze. In this paper, anti-high overload structure of the fuze is designed by analyzing the environmental factors in the electromagnetic launch. Then mechanics analysis and calculation are investigated. Nextly, the finite element simulation model is established. Based on this model, the stresses and deformations of the fuze in different protective conditions are analyzed during a high overload environment. The best protective scheme is selected. The theoretical calculation and simulation analysis results show that the max stress of the structure is less than the tensile strength of the material and the deformation is very small. Finally, the experiment of the electromagnetic launch is executed, and verification of the fuze is ultimately performed. In conclusion, the designed structure of the fuze can meet the anti-high overload requirement.
