摘　　要：当前在引信环境力敏感中,常使用高动态环境下过载作为一级动作要素,通常以惯性模块在过载加速度下的运动行程来作为一级动作使用,惯性模块受限于机械运动,在电气系统中不易集成、可测试性较差。针对以上问题提出并设计了一种基于微机电系统(Micro-Electro-Mechanical System,MEMS)传感器技术,实现引信高动态环境下的动作,介绍了MEMS过载识别系统原理、组成及功能、软件工作流程及地面试验验证情况。试验结果表明,该环境力识别方式适用范围广,可以显著提升引信系统设计灵活性,易于系统集成。Currently,in fuze two levels of environmental force arming,high dynamic overload is often used as one insurance element.Generally,one arming method is used of the inertia mass block’s movement trip under trajectory overload.Mass blocks are limited by mechanical movement and are difficult to integrate in fuze systems,and is poor in testability.A scheme based on MEMS sensor technology is proposed and designed to arm the fuze.The principle,composition,function of the system,software workflow and the test and verify situation are introduced.This method has a wide scope of use can improve the flexibility of fuze systems and is easy to system integration.
