In view of the low utilization rate of fault data and the lack of unified and efficient engineering data support platform in the current equipment reliability engineering, this paper studies the utilization of equipment fault data and the construction of reliability platform. From the key dimensions of personnel allocation, platform database construction, data entry specification, data analysis and information mining, overall composition and core functions of the platform, the construction method and implementation points of equipment reliability platform are expounded, and its engineering application mode in the process of equipment development is discussed. The results show that the research can provide a reference method for building a technical support platform which is suitable for equipment development process and quality management system, and has a certain theoretical and engineering application value for improving the degree and utilization rate of fault data information mining, optimizing equipment reliability design, and further improving the level of equipment quality and reliability.
