利用微机对设备进行故障诊断将有效地提高排故效率,是以经验维修向科学维修方向发展的重要途径之一。利用模糊数学为微机建立数值诊断数学模型的好处是:其输入与输出皆为现场排故中的习惯语言,不需另行检测信息,方便使用利于推广。本文介绍建模的一些主要做法。这种建模方法已由空工院成功地应用在某型飞机机械故障的诊断系统中,实践证明效果良好。 The use of computer-based equipment for fault diagnosis will effectively improve the evacuation efficiency, which is an important way to maintain the direction of scientific maintenance. The advantage of using fuzzy mathematics to establish a numerical diagnosis mathematical model for a microcomputer is that the input and output are both customary languages ​​in the field and do not need to separately detect the information, which is convenient for use and promotion. This article describes some of the major approaches to modeling. This modeling method has been successfully applied to a type of aircraft machinery failure diagnosis system, the practice proved effective.
