摘　　要：为减少传统电梯安全评估方法中的人为影响,真实反映电梯安全状况,建立基于预先危险性分析-故障类型和影响分析(PHA-FMEA)的评估方法。通过分析影响部件的风险指标,研究其量化等级,建立电梯系统综合风险评估模型。以某实际电梯为例,采用该方法进行安全评估并与传统方法作对比。结果表明,该方法与传统方法的评估结论基本一致,但根据风险来定量判断电梯的风险等级,可减少传统方法中人为因素对电梯安全评估结果的影响。In order to reduce the greater impact of hunman factor in traditional method on elevator safety assessment,and reflect duly the elevator safety situation,an elevator safety assessment method based on PHA-FMEA was worked out. Through analyzing indicators that affect component risk and studying of their quantization levels,a comprehensive risk assessment model was established for elevator system. The method was verified by a comparison between both of results obtained with the method and traditional method for a certain elevator. The results show that with the method,the impact of human factors on elevator safety assessment can be reduced.
