摘要:
针对平行于弹轴放置的MEMS安全系统微小型传爆序列设计不便,闭锁机构在内弹道后坐过载环境下闭锁时出现塑性变形等问题,提出了垂直于弹轴放置的MEMS安全系统的离心隔爆滑块闭锁机构。该机构由L型闭锁梁、锁头、刚性定位块组成,在外弹道离心力作用下闭锁时不发生塑性变形,准确定位,保证传爆序列有效对正。通过理论分析了锁头进入锁座的可行性,结合有限元仿真分析和样机实验验证了闭锁机构的功能。仿真实验结果表明,该闭锁机构在达到临界离心加速度时能够实现可靠闭锁,且L型闭锁梁在闭锁时不发生塑性变形。
Abstract:
In order to solve the problems such as the inconvenient design of micro and small detonation sequence of the MEMS security system parallel to the missile shaft and the plastic deformation of the locking mechanism in the internal ballistic recoil overload environment, a centrifugal flameproof sliding block locking mechanism of the MEMS security system perpendicular to the missile shaft was proposed. The mechanism was composed of l-type locking beam, lock head and rigid positioning block. Under the action of external ballistic centrifugal force, no plastic deformation occurs when locking, and accurate positioning ensures effective alignment of the detonation transmission sequence. The feasibility of the lock head entering the lock seat was analyzed theoretically, and the function of the locking mechanism was verified by finite element simulation and prototype experiment. Simulation results showed that the locking mechanism can achieve reliable locking when it reached the critical centrifugal acceleration, and the l-shaped locking beam did not undergo plastic deformation during locking.
