摘要

通过分析研究，确立了汽车交流发电机输出电压纹波幅值可作为故障发生的诊断参数。在物理建模过程中改变结构参数为汽车交流发电机中最常见的电气故障的发生和发展提供了一种建立阈值的方法。实验研究结果证实了解析建立的结构参数与诊断参数之间的关系。对所得数据的分析表明，根据输出电压参数，可以提前诊断出在不久的将来会导致汽车交流发电机失效的故障。

Fault diagnosis in automotive alternators based on the output voltage parameters

Based on analytical studies, it has been established that for automotive alternators the amplitude of the output voltage ripple can be considered a diagnostic parameter indicative of the occurrence of faults leading to its failure. Changing structural parameters in the course of physical modeling provided a way to establish thresholds for the occurrence and development of the most common electrical faults in automotive alternators. Results of experimental research confirm the relationship between structural and diagnostic parameters that was established analytically. Analysis of the obtained data suggests that it is possible to diagnose a fault, which in near future will lead to failure of the automotive alternator, in advance, based on the output voltage parameters.
