摘　　要：建立了基于工作任务模式的雨弹系统可靠性故障树模型,提出了基于BDD故障树的雨弹系统使用可靠度评估方法,并将此方法应用于BL-1A型雨弹的可靠性评估。理论分析评估结果与该型雨弹可靠性鉴定试验结果的相对误差为ε=5.526 797×10-4,二者具有很好的一致性,表明该方法能有效指导雨弹使用可靠性的分析与评估。The reliability failure tree analysis model of rain-enhancement rocket was set up on the basis of the rocket task model. Reliability assessment method of rain-enhancement rocket was proposed by the BDD failure tree analysis. Applying the method to assessment the reliability of BL-1A rain-enhancement rocket, the relative error be- tween assessment results and reliability evaluation test was 5. 526797 × 10^-4, the correctness and effectiveness of the model and method was verified.
