| 摘 要： | 在滚动轴承寿命预测模型分析的基础上,提出了航空发动机主轴承状态寿命的概念,即把主轴承的使用寿命周期划分为状态良好、初步损伤、故障发展和即将失效4个寿命阶段;建立了1种利用机载传感器信息(转速、振动和飞行器机动),来确定航空发动机主轴承使用状态寿命的模型,该模型把状态监控数据和基于理论模型分析计算的方法相结合,为评估主轴承的寿命状态提供了1种新的方法.

| Abstract: | The concept of state life for the aeroengine main bearing was presented based on the analysis of life prediction model for rolling bearing,which meaned the entire service life cycle was divided into four stages: good condition,initial defect condition,damage development condition and forthcoming failure condition.A model was built by using airborne sensor information(speed,vibration and vehicle maneuver) to determine operating state life of aeroengine main bearing.The condition monitoring data and the metho... |
