汽车构件的可靠性用由 A 至 E 字母表示的综合特征来评定,而构件本身的特征则是靠数字表示的状态来评定。构件的特性包括6个特征:A_(1.2)——故障危及或不危及行车的安全性;B_(1.2)——故障是突发的和整车性的,渐发的和局部的;B_(1—4)——故障之间行程或零件的寿命特性〔1——极限的(最短的)和4——无限的(最长的)寿命;Γ_(1.2)——故障已发生,故障已及时防止;Д_(1—3)——寿命期间排除故障的劳动量是大、是小,还是由为数众多的短暂故障积累而
The reliability of automobile components is assessed by a combination of features, denoted by letters A through E, while the features of the components themselves are evaluated by the digital representation of the status. The characteristics of the component include six characteristics: A_ (1.2) - the failure endangers or does not endanger the driving safety; B_ (1.2) - the failure is sudden and vehicle-prone and gradually; B_ ( 1-4) - Lifetime characteristics of the stroke or part between failures [1- - Extreme (shortest) and 4 - Infinite (longest) life; Γ_ (1.2) - Fault has occurred, fault has occurred Timely prevention; Д_ (1-3) - labor-time troubleshooting is large, small, or by a large number of short-term fault accumulation and
