抗干涉齿轮集机构的二维迷宫映射校验方法

2-D MAZE-MAPPING VERIFICATION METHOD FOR THE COUNTER-MESHING GEARS MECHANISM

抗干涉齿轮集机构 (CMG)是一种可用于引信安全点火控制的密码装定 /鉴别机构。本文以一个文献报道的CMG机构实例为例 ,简要介绍了其结构、工作原理与基本概念。提出了适用于校验CMG机构齿牙编码设计的二维迷宫映射方法 ,该方法简捷、易用 ,物理概念清晰。作者还结合同一实例 ,应用此法分析了一些相关重要问题 。

Counter-meshing gears mechanism is a coding and discrimination mechanism, which can be used for safety and arming surety applications. Based on a reported CMG instance, the structure, working principles and essential concepts of the CMG mechanism were briefly educed. The so called 2 dimensional maze-mapping method for CMG teeth-coding verification was presented. The method is simple, clear and easy for use. Applying the method to the same instance, some critical issues were analyzed, and conclusions were given.
