| 1. | This paper adopts fmeca method to eliminate and check fault > catch substantive fault then provide basis for maintenance and replacement decision 本文提出采用fmeca方法进行设备失效事故的排查,抓住主要矛盾,为维修与更新决策提供依据。 |
| 2. | The database provides not only historic operation logs and original characteristic parameters of the cefr ' s equipment , but also curves of equipment fault analysis and equipment reliability parameters 它不仅可以提供了反应堆设备的运行历史记录和原始特性参数,而且还提供设备失效趋势分析曲线和设备可靠性参数。 |
| 3. | Abstract : the out - particles of lubricating grease , which are splashed from rolling bearings or linear motion bearings , adhere to liquid crystal manufacturing equipment or hard disks , resulting in damage to product functions or capability 文摘:滚动轴承或直线运动轴承中的润滑油脂,可能飞溅出颗粒,粘附在液晶制品或硬盘上,导致设备失效。 |
| 4. | One of the main failure patterns is caused by fatigue crack growth , so it is necessary to research material fatigue crack growth rate . so for , it is still a difficult problem to measure crack length at elevated temperature 裂纹疲劳扩展导致的破坏成为设备失效的主要型式之一。因此对材料在高温下疲劳裂纹扩展速率的研究成为工程界的迫切需要。 |
| 5. | Aiming at the situation that non - critical equipment in rms may fail , and assuming that there is a single piece of critical equipment in rms , an effective degradation performance mode of rms is established 针对可重组制造系统中可能存在非关键设备失效的情况,在选取系统中存在单台关键设备的条件下,建立可重组制造系统在一定时期内降级运作的有效性模型。 |
| 6. | The main task of the algorithm is to find how to organize flights departure and how to select a route for each of these flights to minimize the gross loss caused by bad weather or navigation equipment malfunctions 文章前半部分主要介绍解决此问题的理论算法,算法研究的主要问题是在恶劣天气条件或者导航设备失效的情况下如何组织航班放飞以及如何动态地为航班选择航路以使总损失最小。 |
| 7. | Then , according to the requirement analysis , concept design , logic design and database design , the electronic instrument failure rate database was designed and the components failure rates and n factors in gjb / z299b - 98 were established in the database 其次,按照开发关系型数据库所要求的需求分析、概念设计、逻辑设计和物理设计四个阶段,设计了电子设备失效率数据库并做了数据录库工作。 |
| 8. | Based on the kernel interface and the essential application method of the enterprise level event logging system , this paper analysis related knowledgeof data mining method , proposes the connection method and the classified method which are used for to analyze fault data 同时结合eventlogging企业级日志系统的内核空间接口和基本使用方法,研究了数据分析的相关知识,提出分析设备失效数据的关联方法和分类方法。 |
| 9. | Cefr equipment reliability database is used mostly in following ways : providing equipment reliability parameters through equipment operation log and maintenance records analysis for cefr ' s pra and on - line risk monitor system . providing fault causes of related equipment through the equipment fault records and reason analysis in order to control spare parts macroscopically and adopt necessary improvement . providing curves of equipment fault characteristic through historical records of equipment fault for preventive maintenance Erd将是cefr的重要信息系统,它不仅可以提供设备原始特性参数,而且可以提供设备失效趋势分析曲线, erd的主要用途如下: ?通过对设备运行记录和维修记录的分析给出设备可靠性参数,用于cefr的pra分析及风险管理系统; ?通过对设备失效记录及原因分析给出相关设备失效的根本原因,以便从宏观上控制备品备件或采取必要的改造; ?通过对设备失效历史记录的分析给出设备失效的特性曲线,提供预防性维修所需信息; ?另外erd在大修优化、 rcm 、定期试验以及维修政策方面有重要的指导意义。 |
