Abstract:
In view of the shortcomings of pseudofluid delay arming device,based on hydrodynamics formulae,reasonable hypothesis,speciality of magneto-rheological fluid(MRF) and fuze environmental parameters,a delay arming time model of a centrifugal(MRF) delay arming mechanism of fuze is established.The delay formula is deduced.The magnetic circuit is designed by magnetic conductivity method,and the electromagnetic field analytical software Ansoft is used for numerical simulation to validate fuze safety in peacetime and reliability in working.According to the analysis,a new fuze delay arming device using MRF is proposed,which can be used in medium and large caliber fuzes.
