摘要: 针对传统制造系统可靠性评价不考虑加工过程产品质量数据,无法对制造系统可靠性进行及时准确的建模分析,提出了基于过程质量数据的制造系统可靠性建模分析方法.首先,在给出了包含制造产品质量的制造系统可靠性新内涵的基础上,分析了制造过程中关键质量特性检验数据和制造系统组件的退化故障数据等过程质量数据对制造系统可靠性建模的影响,从而明确建模需求.然后,首次提出了基于产品合格概率和制造系统组件退化失效率的制造系统可靠性分析模型.最后,通过某盖板的加工系统的可靠性建模分析验证了模型的有效性.结果表明该模型能够方便地利用制造阶段的质量数据更准确地估计出制造系统可靠性.

Abstract: Aiming at the limitation of traditional reliability analysis of manufacturing systems neither considered product quality, nor implemented accurately comprehensive modeling, a reliability analysis modeling of manufacturing systems based on process quality data was presented. Firstly, the concept of reliability of manufacturing system was expounded and process quality data which impacted on the reliability of manufacturing system was analyzed, such as inspection data of the key quality characteristics, degradation failure data of manufacturing systems component and so on. Then the reliability analysis model of manufacturing systems was firstly proposed based on product qualified probability and manufacturing component degradation failure rate. Finally, a reliability analysis case of a cover plate machining system was given to verify the availability of the model. The results show that the proposed model can get more accurate estimated value of the reliability of manufacturing systems from the quality dada in manufacturing process conveniently.
