航空发动机主轴轴承数据统计处理及寿命评估

Statistics Process to Actual Measuring Data and Life Evaluation for Spindle Bearing Used in Aeronautical Engine

航空发动机主轴轴承台架试验费用昂贵且多为小子样无失效 ,在此情况下讨论其分布函数实为困难。因此 ,由现场收集大量的使用数据 ,以初步探讨其寿命分布规律及其可靠性水平 ,为航空发动机轴承可靠性研究打下了基础。附表

The expense of platform test for the spindle bearing used in aeronautical engine is high and the many tests are small sub specimens and no failure, in this case, it is difficult to estabilsh the distributed function. Thus, the large amount data are collected in the site to research the life dist riburtion rule and reliability level, this makes the foundation for reliability study of aeronautical engine bearings.
