关 键 词：Delay arming time Magnetorheological fluid fuze Self-regulation Magnetic field
摘 要：正With the development of science and technology,its performance of delay arming device has been continually ***,bore premature,premature detonation,failure to fire and other grave accidents have still often happened in recent *** reason is that delay arming device prematurely rescinds fuse safety mechanism or its fail of delaying arming *** has been widely focused on how to improve its safety and reliability of delay arming device at home and abroad,but there have only been few researches on its self-regulation of delay arming *** on its principle of MR fluid damp controlling technology and its yield stress of MR fluid will be changed with its changes of magnetic field strength,design and simulation of magnetic circuit for MR fluid fuze has been done in this *** this model among input current of coil,discharge aperture and time of discharge has been obtained by test and some useful results are made by numerical *** experimental results prove that its delay arming time of MR fuze meets the design requirements and indicate that input current of coil has an obvious effect on discharge time.
