中文摘要:
      本文将可拓层次分析法的迭代模糊综合评价模型(AHP-FCE)应用到设备重要度的评价中。量化了判断矩阵中的打分因素,增加了判断矩阵中各个元素的可靠性。首先建立评价目标,对机组子系统进行划分。然后在传统的重要度评估方法加以改进,运用AHP-FCE的方法,并进行随机抽样赋权计算,确定功能重要相关项(FSI)。其次进行故障模式影响及危害性分析(FMEA),确定风险等级和故障影响。在此之后,采用最小二乘法来拟合数值模拟的故障时间点,通过威布尔分布模型来求解压缩机各零部件的寿命模型,并对活塞环的寿命求解,验证了构建维修周期模型是可行的。最后修订了维修大纲和计划。结果表明改进后的方法是可行的,从更加公平客观的角度为日后往复式压缩机的设计、制造、生产使用及维护给予了指导性的建议。
英文摘要:
      The iterative fuzzy comprehensive evaluation model of extension analytic hierarchy process (AHP-FCE) is applied to the evaluation of equipment importance. The scoring factors in the judgment matrix are quantified and the reliability of each element is increased. The results are introduced into the reliability-centered inspection and maintenance strategy (RCM), and put forward the preventive countermeasures of the main fault consequences, optimize the inspection and maintenance program. Firstly, the evaluation objective is established and the subsystem of the unit is divided. Secondly, the AHP-FCE method is applied to improve the traditional importance evaluation method, and the weight calculation of random sampling is carried out to determine the functional significant item (FSI). Then, failure mode and effects analysis (FMEA) is carried out to determine the risk level and fault impact. After that, the least square method is used to fit the fault time point of numerical simulation. By using Weibull distribution model to solve the life model of compressor parts and piston rings. The result shows that the improved method is feasible, and gives some guidance for the design, manufacture, production and maintenance of reciprocating compressor from a more fair and objective point of view.
