| 摘 要： | 详细分析和讨论了柴油机缸盖振动信号的特点，对其进行了小波包分解，得到时－频分布图，并基于此，提出运用图像处理技术进行内燃机的状态监测与故障诊断的方法，建立了基于图像匹配的内燃机气阀机构诊断模型，并将其和于６１３５Ｇ柴油机气阀机构的故障诊断。结果表明，该方法物理意义明确，诊断结果精度较高，速度快，为内燃机的状态监测与故障诊断找到了一条新的途径。

| Abstract: | Characteristics of vibration signal measured on cylinder head is analyzed in this paper.Wavelet packet algorithm is utilized to decompose the vibration signal and get the time-frequency distribution image.A new diagnosis method using image processing technology is proposed.Based on that,a valve fault-diagnosing model for a 6135 diesel engine is set up.The results verify that this method has a clear physical meaning and is of relatively high diagnosing accuracy. |
