摘要

文章介绍了利用振动声学特性对柴油燃料设备进行技术诊断的实际结果。作者使用给定的诊断矩阵、贝叶斯方法和序列分析计算了降低喷油器弹簧弹性对喷油器性能的影响,以及 "喷油器弹簧张力增加 "诊断与 "频率为 115 Hz 时振幅较大 "符号之间的联系。

Probabilistic and Statistical Methods for Identifying Defects in Diesel Fuel Equipment Using Vibroacoustic Spectra
The article deals with the practical results of technical diagnostics of diesel fuel equipment using vibroacoustic characteristics. The authors used given diagnostic matrix, Bayesian methods and sequential analysis to calculate the effect of reducing the elasticity of the injector spring on the performance of the fuel injector and the connection of the diagnosis “increased injector spring tension” with the sign “high amplitude at a frequency of 115 Hz”.
