摘要
在介绍对TB/T 2468—1993《铁路信号产品可靠性要求评定方法》修订背景及原则的基础上,从元器件失效率评定及信号产品可靠性试验的定时截尾试验方案、序贯截尾试验方案、平均无故障工作时间的点估计及置信限、电子类信号产品可靠性评定方法、信号产品可靠性现场数据统计分析法等方面,介绍新标准TB/T 2468—2018《铁路信号产品可靠性要求评定方法》主要修订内容及典型试验方案数学原理,并给出新标准实施建议。
On the basis of the revised background and principles of TB/T 2468—1993 Evaluation Methods of Railway Signal Product Reliability, from component failure rate assessment and the fixed time terminated test plans, sequential test plans of signal products reliability test, point estimation and confidence limits of MTBF, electronic signal product reliability assessment methods, signal product reliability field data statistical analysis methods, etc., this article introduced the revise content of TB/T 2468—2018 Evaluation Methods of Railway Signal Product Reliability and the mathematical principles of the typical test plans, and gave some suggestions of implementation.
