摘　　要：由于装甲车辆综合电子系统具有耦合性强、动态离散和复杂度高的特点,其难以采用静态故障树方法进行系统可靠性分析,针对这一难题,运用动态故障树方法对系统可靠性进行了分析判别,并运用随机Petri网建立了故障树的仿真模型。以某型车辆为例,通过仿真实验得出了综合电子系统的故障率和可用度指标的动态变化曲线,其分析结果为系统可靠性与测试性设计提供了理论参考。The integrated electronics system of armored vehicles has characteristics of strong coupling, dynamic discreteness and high complexity, it is difficult to analyze the reliability of the system by means of static fault tree. To solve the problem, the authors analyze the reliability of the system by means of dynamic fault tree, and build the simulation model of dynamic fault tree with stochastic Petri net. Taking certain type of armored vehicles as example, the authors obtain dynamic curves of failure rate and availability by simulation experiment. The analytic results can provide theoretical reference for reliability and test design of the system.
