摘　　要：基于过程故障模式、影响及危害性分析(PFMEA)方法,对载人运载火箭发射场总装工作进行易错风险识别及影响分析。针对载人火箭总装可能发生的故障模式、形成原因及对火箭发射造成的所有影响,综合考虑易错风险的优先等级和综合评估系数(RPN)值的大小,对易错项目及工艺薄弱环节进行识别并制定改进措施,进而提高了载人运载火箭发射场总装工艺的质量和可靠性。Based on the Process Failure Mode,Effect and Criticality Analysis(PFEMA),the error-prone risk identification and impact analysis of the general assembly work at the manned launch site of the launch vehicle are carried out.For the possible failure modes,causes and all the impacts on the product during the general assembly process,the error-prone items and process weak links are re-identified and improvement measures are formulated according to the size of the Risk Priority Number(RPN)value of the failure mode,thereby improving the quality and reliability of the general assembly process at the manned launch site of the launch vehicle.
