摘　　要：针对试验中引信MEMS滑块隔爆机构悬臂梁和卡头出现较大变形导致隔爆滑块运动不到位的情况,提出一种改善强度的滑块隔爆机构。该机构改善了悬臂梁尾端形状,将悬臂梁结构由原来的"直钩"型改成"弯钩"型,加大了卡头双翼的厚度以及张开角度。仿真结果表明:改善后的悬臂梁尾部不会被基板凸台卡住,卡头能顺利进入基板卡座,隔爆滑块在离心过载的作用下运动到位并锁定。Aiming at the situation that the MEMS explosion interrupter uesd in fuze couldn＇t move in-position during the test,which was caused by the deformation of the cantilever and the lock,a explosion interrupter with improved strength was put forward. The caudal shape of the cantilever was improved, changing the structure from ＂straight hamulus＂ to ＂bend hamulus＂. The thickness and the patuious angle of the lock was enhanced. Simulation results showed that the improved caudal shape of the cantilever could not be seized by the boss, and the improved lock came into the locker successfully. The explosion interrupter moved in-position under the action of centrifugal load and was locked.
