摘要/Abstract

摘要： 维修是保持或者恢复产品技术状态的重要手段。为了掌握定期维修条件下产品的可靠性规律，从产品失效原因出发，在充分考虑维修后产品性能退化量变化特点的基础上，利用复合Poisson过程建立了该条件下产品的性能退化规律模型，进而得到可靠度和失效率指标。通过比较分析维修前后的失效率变化规律，给出了描述维修效果的解析表达式。以某水泵转子为例，通过进行数值分析，验证了该方法不仅能够较好地描述定期维修条件下转子的可靠性规律，而且还可以准确直观地描述维修效果，为使用方制定维修策略提供一定的理论依据。

Abstract: Maintenance is a good means to retain or recover the product state. In order to understand the reliability law of products under the condition of periodic maintenance, a performance deterioration rule model is established based on the composite Poisson process. In the model, the failure mechanism and the product deterioration character are fully considered in the case of periodic maintenance. The model can be used to determine the reliability and failure rate. An analytical expression, which can specify the maintenance effect, is presented by analyzing the change law of failure rate. The model can exactly describe the reliability law of product by taking the pump rotor for example. It also can portray the maintenance effect more objectively and intuitively.

Key words: applied statistical mathematics, imperfect maintenance, state recovery, performance deterioration, recovery factor
