坠落冲击环境下引信保险系统的可靠性仿真

Reliability Simulation of Fuze Safety and Arming System under Drop-down Shock Environment

安全性是引信最基本的要求之一。该文以某引信冗余保险系统为例 ,对其进行了不同落高、水泥、沥青、土壤和钢板介质、45°倾斜坠落实验。在此基础上 ,建立引信独立冗余保险系统的动力学模型 ,并进行了可靠性数值仿真。

Safety is one of the most important characteristics of fuzes. Taking the independent redundancy safety and arming system of a certain fuze for example, the paper sets up the dynamics models of setback mechanism and centrifigual mechanism, evaluates its safety after making reliability simulation upon falling down in oblique pose from different altitudes to several mediums. The paper is of practical value for deeply studying the reliability of fuze's safety and arming system.
