基于滤波模型的航空制导弹药剩余寿命分布

Residual Life Distribution for Air Guided Ammunition Based onFiltering Model

摘要:

如何更好地利用技术检测数据来预测航空制导弹药剩余寿命,这是弹药质量控制研究中的一个重要方向。利用动态主成分分析法提取了航空制导弹药状态检测参数主成分,解决了弹药检测参数冗余、相互关联的问题,为剩余寿命分布研究奠定了基础。基于滤波模型和威布尔分布以及正态分布,建立了航空制导弹药剩余寿命分布模型。通过实例,就能很好地将弹药剩余寿命分布与弹药故障联系起来,并动态掌握其剩余寿命分布情况。

Abstract:

How to make better use of test data to predict Residual life of Air Guided Ammunition is an important directionfor Ammunition Quality control. We extract principal component for text data of Air Guided Ammunition by Dynamic prin.cipal component analysis (DPCA), which solve the problem as Detection parameter redundancy and inter relating, besides,which lays the foundation for the research of Residual life distribution. The Residual life distribution model was estab.lished based on Filtering model, WEIBULL distribution, and Normal distribution. We can commendably associate Residu.al life distribution with faults, and dynamically grasp of Residual life distribution.
