摘　　要：探测器阵列靶是测量激光强度时空分布的常用设备,电路系统作为其重要组成部分,其可靠性是影响探测器阵列靶能否高效稳定运行的关键因素之一。本文首先对电路系统进行了故障模式及影响分析(FMEA),获得不同模块对系统整体可靠性的影响。为计算电路系统的可靠度,引入了每个模块的重要度,并在对模块重要度进行分析时,对传统AGREE分配法中的重要度进行了改进。随后根据改进的AGREE分配法,对可靠度指标进行分配,对不满足可靠度指标的模块,采用冗余设计提高它们的可靠度。最终使得电路系统工作5 h的可靠度由0.99931830提高到0.99996730。本研究为探测器阵列靶电路系统的可靠性设计与分配提供了方法与依据。Detector array target is a common equipment for measuring the spatiotemporal distribution of laser intensity,and as an important part of detector array target,circuit system's reliability is the key to the efficient and stable operation of detector array target.Firstly,the failure mode and effect analysis(FMEA)of the circuit system is carried out to obtain the influence of different modules on the reliability of the overall system.In order to calculate the reliability of the circuit system,the importance of each module is introduced,and the importance of the traditional AGREE allocation method is improved when analyzing the importance of each module.Subsequently,according to the improved AGREE allocation method,reliability indexes are assigned,and redundancy design is used to improve the reliability of the modules that do not meet the reliability index,so that the reliability of the circuit system operating for 5 h is increased from 0.99931830 to 0.99996730.This study provides a method and basis for the reliability design and distribution of detector array target circuit systems.
