摘　　要：针对HXD2电力机车牵引通风机及电机系统,根据NSWC98标准,建立了系统的可靠性模型并引用NPRD数据计算出系统的故障率λ和MTBF时间;引用系统中各单元的实际维修时间数据,计算了系统的MTTR和可用度A;根据ASCE APM和CEI EN50126标准,对系统的风险进行了评价;基于故障树分析,对系统的"散热不良"和"噪音超标"2个顶事件对机车的影响进行了安全性评估.As for the traction motor fan ＆ its motor system of HXD2 electric locomotive, a reliability model of the system is created based on NSWC98, and the failure rate （λ） and MTBF time are calculated based on NPRD data. The MTTR and Availability （ A ） are calculated based on the site maintenance period of every unit in the system. By the ASCE APM ＆ CEI EN50126 standards, the risk of the system is assessed. The safety evaluation of the effect of the two top events of the system： bad cooling and serious noise, on the locomotive is conducted based on failure tree analysis.
