研究原子吸收光谱法在汽车自动变速器故障检测中的创新性应用。 通过原子吸收光谱法测定行驶里程分别为10 000～15 000, 20 000～26 000, 32 000～38 000, 43 000～49 000, 52 000～58 000 km五批奥迪A6自动变速器油液(ATF)中主要金属Fe, Cu, Cr的含量, 建立奥迪A6自动变速器不同行驶里程数ATF主要金属含量的数据库。 研究发现主要金属含量随着汽车行驶里程数上升而增加, 并且其正常含量在两条趋势线之间。 测定有故障症状的ATF主要金属含量, 并与其数据库数值比对, 既可以判断自动变速器的磨损状况, 也可以帮助汽车检测维修人员在不解体状态下诊断汽车自动变速器的故障原因, 降低汽车维修成本, 提高维修质量。

The authors studied the innovative applications of atomic absorption spectrometry in the automatic transmission fault detection. After the authors have determined Fe, Cu and Cr contents in the five groups of Audi A6 main metal in automatic transmission fluid whose travel course is respectively 10~15 thousand kilometers, 20~26 thousand kilometers, 32~38 thousand kilometers, 43~49 thousand kilometers, and 52~58 thousand kilometers by atomic absorption spectrometry, the authors founded the database of primary metal content in the Audi A6 different mileage automatic transmission fluid (ATF). The research discovered that the main metal content in the automatic transmission fluid increased with the vehicles mileage and its normal metal content level in the automatic transmission fluid is between the two trend lines. The authors determined the main metal content of automatic transmission fluid which had faulty symptoms and compared it with its database value. Those can not only judge the wear condition of the automatic transmission which had faulty symptoms but also help the automobile detection and maintenance personnel to diagnose automatic transmission failure reasons without disintegration. This reduced automobile maintenance costs, and improved the quality of automobile maintenance.
