在实行以状态为基础的维修方式时,仅仅有合适的检测和诊断仪器设备还是不够的.检测和诊断仪器可以得到某部位或整机性能的一些参数实测值(如温度、压力、运行间隙、振动和油液质量等)是否超过了一定程度(技术标准),但一般来说,这还不能直接判断是否要维修和采取什么级别的维修.为此还需要一个决策过程.目前在实际工作中,这个决策过程通常是依靠人的经验来完成的.由于“技术状态”是一个模糊的概念,判断时往往因人而异,有很大的随机性.为了使决策更科学化,需要将这种经验的决策提高一步,即利用模糊数学原理,将技术状态定量化,然后作出合理的判断.为此,本文提出“劣化度”概念,用劣化度来衡量设备各部位或整机对各种技术状态的隶属度,
In the implementation of state-based maintenance methods, it is not enough to have suitable testing and diagnostic equipment, which can be used to obtain the measured values of some parameters such as temperature, pressure, running clearance, Vibration and fluid quality, etc.) exceeds a certain level (technical standards), but generally speaking, this can not directly determine whether to repair and take what level of maintenance.To this also requires a decision-making process.Now in actual work , This decision-making process is usually to rely on human experience to complete.As the “state of technology” is a vague concept, judgments often vary from person to person, with great randomness.In order to make the decision-making more scientific, it needs to be The kind of experience to make decisions one step forward, that is, the use of fuzzy mathematics, the state of technology to quantify, and then make a reasonable judgment.To this end, this paper presents the concept of “degree of deterioration”, using the degree of deterioration to measure the various parts of the equipment or machine to various The degree of membership of the technical state,
