基于油液光谱数据的综合传动装置的可靠性

Reliability analysis of power-shift steering transmission based on spectrometric oil data

综合传动装置具有高可靠性的特点,其在可靠性试验中经常出现失效数据少甚至零失效的现象。油液的光谱分析技术可以记录综合传动装置寿命试验过程中的产品性能退化信息,油液光谱数据可以用来建立性能退化可靠性模型。本文采用基于性能退化数据的可靠性评估方法,通过对传动装置油液光谱分析中Cu元素浓度进行退化轨道建模,实现了综合传动装置的可靠性评估。

The power-shift steering transmission has the characteristics of high reliability so that few failures can happen in the traditional life testing.Spectrometric oil analysis is adopted to record the performance degradation information of power-shift steering transmission in the life testing,and spectrometric data can be used to establish the performance degradation reliability model.Based on the method of performance degradation data analysis,the degradation model of Cu PPM is established and the reliability of a power-shift steering transmission is assessed.
