Title  Foreign trade inpidual rocket warhead fuze system design and analysis and calculation             

Abstract In order to improve the fuze safety design,flameproof,redundancy insurance,self destruction mechanism and the vast fire device。The design of two degrees of freedom spring inertia cylinder insurance mechanism ensures the safety of service。In order to do a good job in the relevant design requirements,understand foreign mechanical fuze related characteristics analysis,and combined with the current situation in China,and various parts of the fuze design,fuze flameproof mechanism adopts a vertical rotor, insurance institutions based on recoil insurance and insurance。The inertial firing mechanism to achieve self destruct。Has made the design of fuze。And through the calculation of the reliability of the fuze,including storage reliability, when launching。Through the calculation of dimension chain, ensure each parts of fuze can reasonable and reliable assembly。Finally, the overall analysis and calculation show that the fuze can achieve normal safety,reliable effect。Fuze safety adaptability in line with national military standard "Safety fuse design criteria" and "bad fuse Habitat and performance test method "requirements。
