摘　　要：针对某型火箭外测系统设备故障现象,在对服务器A启动缓慢故障原因分析的基础上,建立了层次故障树模型,开展了定性分析和针对性故障验证试验,确定了该故障发生的原因,并采取了有效的措施保证火箭测试工作的正常进行。实践证明,运用故障树分析法能够快速定位故障原因,为改进外测系统设备在低温条件下工作的可靠性提供重要支撑。Aiming at outer ballistic measurement system equipment fault phenomenon of a rocket,the layer fault tree model is set up based on the analysis of the fault cause of the server A starting slowly,and a qualitative analysis and the corresponding fault verification tests are implemented.The cause of the fault has been identified at last and the effective measures are taken to guarantee the normal of the rocket test work.The result demonstrates that the fault tree analysis can quickly locate the fault cause,which provides an important support for improving the reliability of outer ballistic measurement system equipment under a low temperature.
