摘　　要：为更好地量化分析电梯系统的安全性,真实地反映电梯安全状况,将故障类型、影响和危险度分析(FMECA)方法应用于电梯安全评估。研究深入细化了电梯安全评估子系统划分、故障类型及原因分析、故障概率及危险度分析、风险评估和风险控制等程序。经适用性研究,得出的电梯综合风险等级与电梯实际运行状况一致。To quantitatively analyze the safety of lifts and truly reflect lift safety conditions,the failure mode,effect and criticality analysis(FMECA)is applied to lift safety assessment.The procedures of subsystem division,failure mode and effect analysis,failure probability and risk analysis,risk assessment and risk control are deeply detailed.Through the applicability study,the comprehensive risk levelis consistent with the actual operating condition of the lifts.
