摘要
基于发射过程引信保险机构的工作原理,设计一种应用于双环境力下的MEMS执行器,建立了该执行器中后坐机构和钟表机构的动力学模型,研究了影响后坐机构和钟表机构工作的因素。应用ADAMS软件下对MEMS执行器进行动力学仿真分析,得到后坐滑块和齿轮的运动曲线。计算结果表明,后坐机构能够在后坐环境下可靠执行动作并运动到位,钟表机构能够在在离心环境下达到设计要求的延时时间并能够可靠运动到位。同时,该执行器在勤务处理时是安全可靠的。
Based on the working principle of fuze safety mechanism in the emission process , a kind of MEMS actuator applied in dual environment forces was designed. The dynamical model of the recoil and timepiece mechanism was established, and the main factors concerning the operation of the recoil and timepiece mechanism were analyzed. The dynamic analysis of MEMS actuator was accomplished by the ADAMS, and the motion curves of recoil and gear were obtained. The calculation results show that the recoil and timepiece mechanism can work under the setback environment and centrifugal environment normally, and move to the designated place. At the same time, the MEMS actuator is safe and reliable in the service process.
