摘要
本文针对引信发火控制电路中微执行器输出力矩弱的特点,利用微沟道和凝胶纤维把化学能转化成机械能形变技术,设计了一种新型MEMS微执行器。这种微执行器是通过静电力克服机械弹性力使极板产生相对运动,控制发火控制电路的导通;利用凝胶纤维的收缩力解除引信发火控制电路保险从而达到开启和关闭的目的。文中对所设计的结构进行ANSYS仿真,验证它的可行性并优化了结构参数。这种新型微执行器最大的特点是功耗小,输出功率大,具有很高的机械效率。
This paper aimed to characteristic of micromachining weak force moment in the fuse circuit that control of catch fire, and by making use of micro channel and gel fiber made chemical energy change into mechanical energy, designed a new kind of MEMS micromachining. This kind of micromachining had electropolar board could move relatively by making use of electrostatic force overcoming the machinery elastic force, control the conduction of the circuit ; made use of retractile force of the fibrous gel to free - form circuit safety and then achieved the aim of turn on and turn off. The paper also took the micromachining structure into ANSYS simulated, proved its feasibility and optimized its structural parameter. The maximal characteristic of this kind of new type micromachining is that it＇s power consumption is small, comparing with the current device it has made use of gel fiber makes it consume very few the energy and has very high of mechanical efficiency.
