Rolling bearings — Explanatory notes on ISO 281 — Part 2: Modified rating life calculation, based on a systems approach to fatigue stresses 滚动轴承——ISO 281第2部分:基于疲劳应力系统方法的改进额定寿命计算的说明

                除了寿命修正系数a1之外，ISO 281:2007还引入了基于系统寿命计算方法的寿命修正系数aISO。这些因素应用于修正的额定寿命方程，Lnm=a1aISOL10。ISO 281:2007中给出了一系列可靠性值的可靠性修正系数a1，以及评估系统修正系数的方法方法aISO。L10为基本额定寿命。
ISO/TR 1281-2:20 08提供了关于a1和aISO推导的补充背景信息。

ISO 281:2007 introduced a life modification factor, aISO, based on a systems approach to life calculation, in addition to the life modification factor, a1.These factors are applied in the modified rating life equation, Lnm = a1aISOL10. The modification factor for reliability, a1, for a range of reliability values, is given in ISO 281:2007 as well as the method for evaluating the modification factor for systems approach, aISO. L10 is the basic rating life.
ISO/TR 1281-2:2008 gives supplementary background information regarding the derivation of a1 and aISO.
