利用计算机进行机械故障数值诊断,是近年发展起来的工程设备自检的重要方法之一。它是利用信息论、数据处理技术以及计算机这个强有力的工具,对有故障或即将发生故障的设备,根据其外观征兆、检测信息,进行数学加工分析,做出定量计算。 机械数值诊断方法与维修人员凭借个人经验诊断不同。经验诊断是根据设备的外观征兆和已有的检测数据,从个人的经验出发,做出最可能的判断。诊断的准确性与个人的学识、专业、经验、责任心等有直接关系;而机械数值诊断的专家系统,是集众多技术能手的经验,并将其提高到科学的理论体系,达到具有普遍使用的目的。因此,排除了个人诊断中的主观因素,而更接近于客观实际。但是,机械数值诊断过程与个人诊断过程也有相似的地 The use of computer numerical fault diagnosis of mechanical failure is developed in recent years, one of the important methods of engineering equipment self-test. It is the use of information theory, data processing technology and computer this powerful tool for faulty or impending failure of equipment, according to the appearance of signs, testing information, mathematical processing analysis, to make quantitative calculations. Mechanical numerical diagnosis methods and maintenance personnel rely on personal experience to diagnose different. Experience diagnosis is based on the appearance of the equipment and the existing test data, starting from the personal experience, to make the most likely judgments. Diagnostic accuracy and personal knowledge, expertise, experience, sense of responsibility has a direct relationship; and mechanical numerical diagnosis expert system, is a collection of many technical experts experience, and to enhance its scientific theoretical system, with universal use the goal of. Therefore, the subjective factors in the personal diagnosis are excluded, which are closer to the objective reality. However, there are similarities between the mechanical value diagnosis process and the personal diagnosis process
