一种基于油液光谱分析和免疫原理的内燃机磨损故障诊断方法

人工免疫系统(AIS)具有分布性、自适应性和动平衡性等特点,通过在油液分析领域引入免疫原理,将油液光谱分析的正常数据和故障数据分别作为AIS的自己串和非己串,进化学习后生成典型故障条件下的成熟检测器,并依据该检测器对某型军用内燃机油液分析数据进行了故障诊断.应用结果表明:新的内燃机故障诊断方法能够有效分辨出故障数据,取得了很好的故障诊断效果.

A Fault Diagnosis Approach of Engine Using Immunological Theory and Spectrometric Oil Analysis

Artificial immune system(AIS) is a new computational intelligence approach which uses ideas gleaned from immunology and has advantages in performing a wide range of tasks in various areas of research.In this paper,AIS was applied in wear fault diagnosis of engine and propose a new wear fault diagnosis approach using immunological theory.An immune algorithm for the problem was proposed and was used for fault detection of an engine.The results show that the approach using immunological theory can detect the wear fault correctly.
