摘要

测量本身导致设备性能退化的情况是存在的,然而这个问题往往被研究者们所忽视。文中针对这种情况下的剩余寿命建模进行了研究。首先,在自然退化模型的基础上建立有损测量退化模型;其次给出了相应模型的参数估计方法和基于贝叶斯理论的设备剩余寿命的实时更新方法。最后通过一个仿真示例证明了研究这个问题的意义和文中建模的有效性。

Abstract

The equipment's performance degradation incurred by measurement usually exists. However, this problem is often ignored by researchers. The residual life model considering this situation was studied in this paper. Firstly, a damage measurement degradation model was presented on the basis of the natural degradation model. Then the parameter estimation method for the proposed model and real-time updating method for the equipment's residual life based on Bayes theory were given. Finally, a simulation example was used to testify the significance of this research and the validity of the proposed model.

Key words： damage measurement; residual life; Bayes method; real-time updating
