摘要:

坦克发动机故障目前维修模式落后,故障确诊困难.通过大量试验研究,得出了坦克发动机常见故障在缸体表面、缸盖系统等的振动机理及其信号特征,并研究了气门漏气、发动机拉缸、运转不平衡等常见故障的信号特征,选取了相关、频域、小波等信号分析方法,并以喷油过早、喷油不正常、后燃型、发动机缸体、高压油管振动信号的频域分析等实例证明了信号特征及其分析方法的适用性和有效性.

Abstract:

Tank engine failure is currently backward in maintenance mode, and fault diagnosis is difficult. Through a large number of experimental studies, the vibration mechanism and signal characteristics of common faults of tank engines on the surface of the cylinder block and cylinder head system were obtained, and the signal characteristics of common faults such as valve leakage, engine cylinder pulling and running imbalance were studied, and signal analysis methods such as correlation, frequency domain, and wavelet were selected, and examples of premature fuel injection, abnormal fuel injection, after-combustion type, engine block, and high-pressure oil pipe vibration signal frequency domain analysis proved the applicability and effectiveness of signal characteristics and their analysis methods.
