摘要
针对小口径榴弹引信安全与解除隔离装置(安解装置)体积缩小的同时加强冗余保险性能和结构强度的要求,提出了一种基于电铸镍材料的改进型限位自闭锁式引信MEMS安解装置.装置利用后坐环境和离心环境激励特点,加以指令控制的电动推销器实现三道独立冗余保险和延期解除隔离功能需求,区别于传统隔爆机构需要借助额外微弹簧辅助锁紧,该装置隔爆机构借助一种反锁卡簧结构实现限位自闭锁,且能够实现环境激励下的无碰撞反弹一次闭锁到位.利用刚柔耦合动力学和有限元仿真模拟并加以样机试验的手段,探究在规定的技术指标下安解装置的解保动作和闭锁强度.仿真与样机试验结果均表明:所提装置可识别正常发射的后坐和离心环境激励,满足安全解除保险的动作要求且不会发生材料强度失效,该安解装置简单可靠.
Abstract
Aiming at the requirements of reducing the volume of small-caliber grenade fuze safety and arming device(S&A device)while strengthening the redundancy safety performance and structural strength,we propose an improved self-locking and positioning fuze MEMS S&A device based on electroformed nickel material.The device makes use of the recoil environment and centrifugal environment excitation characteristics,to the command-controlled electric pusher to achieve three independent redundancy safety features and arming delay functional requirements,unlike traditional explosion-proof mechanisms that require additional micro-spring assisted locking,this device's explosion-proof mechanism achieves self-locking and positioning with a counter-locking circlip structure,and is capable of locking in place at once without collision rebound under environment excitation.With the help of rigid-flexible coupled dynamics and finite element simulation and prototype experiment,the arming action and locking strength of the S&A device are investigated under the specified technical specifications.Simulation and prototype test results show that:the proposed device can identify the recoil and centrifugal environmental excitation of normal launch,meet the arming action requirements without material strength failure,the S&A device is simple and reliable.
