摘要
用模式识别的理论和方法,对内燃机气门间隙的识别问题进行了探讨。在分析气门振动力学模型的基础上,通过测取振动信号获得故障特征信息,用模式识别的理论和方法,在建立状态特征模式空间的基础上实现对故障的分类识别。考虑到内燃机振动信号的复杂性,采用了外触发采样和有效截取的方法进行信号的数据采集和分析。
In this paper, the faulf diagnosis of the internal combustion engine with the application Of the theory of pattern recognition is discussed. A method which is practical for obtaining and recogizing the fault charateristics has been introduced. and a special kind of method of prooessing has also been introduced.
