基于系统状态信息的可靠性分析方法研究

Research on Method of Reliability Analysis Based on System State Information

在无失效的情况下如何对产品进行可靠性分析,对于建立在失效数据分析基础上的现有可靠性理论来说,是一个有一定难度的问题。考虑到设备使用中可以方便地监测其系统的状态参数,本文提出了一种利用设备状态信息进行可靠性分析的方法。通过系统参数漂移量的统计分析,推导出基于参数漂移量的可靠度分析模型,以一个具体电子系统为例,说明了方法的实用性。

It is difficult how to analyze the product reliability under the zero-failure data with the current reliability theory founded on failure data analysis. Considering that the systematic state parameters can be monitored conveniently in using the equipment, a method of reliability analysis was proposed by the equipment state information. A probability analysis model based on the parameter drift was deduced by statistical analysis of the systematic parameter drift. Taking a concrete electronic system as an example, the practicability of the method was illustrated.
