基于失效模式与后果分析的混合燃料发动机风险分析
|
摘要
针对发动机在使用混合燃料过程中存在的潜在失效模式和故障风险,尝试以改进失效模式与后果分析(FMEA)模型展开风险分析.基于模糊集理论、灰色关联分析和决策试验与评价实验室方法构建改进FMEA模型,将专家定性评价转化为定量指标并进行风险优先值(RPN)、关联度和原因度的计算.将计算结果进行风险排序和比较,由此揭示了使用混合燃料的发动机的风险排序,进而对潜在的失效模式提出风险控制建议.
An improved failure mode and effect analysis(FMEA) model was designed to analyze the potential failure modes and risks of the blended fuel engine. The FMEA model was established based on the fuzzy theory, grey relational analysis(GRA), and decision making trial and evaluation laboratory(DEMATEL). The experts' qualitative evaluation was translated into quantitative index and was then used in the calculation of the risk priority number(RPN), relevancy degree, and reason degree. The rank of the calculation results showed the risk prioritizing of the blended fuel engine. Corresponding risk control recommendations were proposed.
