摘　　要：提出了一种车辆发动机的故障数据分析方法,包括同一零件不同故障模式故障分布统计分析方法和平均首次故障工作时间(里程)的估计方法。通过对发动机累积故障数据的分析,可以得到故障件的故障分布规律,预测其平均首次故障时间(里程),并判断故障发生的原因,从而为故障的排除提供依据。应用证明该方法有助于提高发动机的故障诊断效率,降低发动机维修成本。An analytical method of the fault data for a truck engine is presented which includes the statistical analysis method of the fault distribution for the different fault modes of the same part and the estimation method of the mean time to first failure. Based on analyzing the cumulative data of the engine failure, it can be obtained that the fault distribution rule, predicted that the mean time to first failure and judged that the fault causes of the failure part, which provides a foundation for engine trouble eliminating. The application shows that the above-mentioned method can improve the fault diagnosis efficiency and redttce the maintenance cost of the engine.
